Absorption And Adsorption Adsorption is the adhesion of molecules of gas, liquid, or dissolved solids to a surface. This process creates a film of the adsorbate (the molecules or atoms being accumulated) on the surface of the adsorbent. It differs from absorption, in which a fluid permeates or is dissolved by a liquid or solid. The term sorption encompasses both processes, while desorption is the reverse of adsorption. Similar to surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent, or metallic) of the constituent atoms of the material are filled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature of the bonding depends on the details of the species involved, but the adsorption process is generally classified as physisorption (characteristic of weak van der Waals forces) or chemisorption (characteristic of covalent bonding). Adsorption is present in many natural physical, biological, and chemical systems, and is widely used in industrial applications such as activated charcoal, capturing and using waste heat to provide cold water for air conditioning and other process requirements (adsorption chillers), synthetic resins, increase storage capacity of carbide-derived carbons for tunable nanoporous carbon, and water purification. Adsorption, ion exchange, and chromatography are sorption processes in which certain adsorbates are selectively transferred from the fluid phase to the surface of insoluble, rigid particles suspended in a vessel or packed in a column.

This process creates a film of the adsorbate on the surface of the adsorbent. This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent), respectively.

READ!!: WATCH IN 720P! This is a brief Introduction to adsorption, showing the basics for anyone with no prior knowledge to adsorption, and without the technical knowledge. Comment and like it and subscribe. All images have been either produced by me or used under no copyright. Here's a more in-depth introduction: Adsorption is a phenomenon whereby free particles (solid molecules/ liquid/ gas molecules) are attracted and bind with the surface; or it can be simply defined as condensation of particles on free surfaces. The phenomena of adsorption can be observed in everywhere from the charcoal deodorizer to the fixed bed contaminant removal in chemical industries. Adsorption involves two components — adsorbate (particle that is being adsorbed) and adsorbent (the surface provided for the adsorption). Adsorption is a surface phenomenon. It arises due to the presence of unbalanced forces at the surface. These unbalanced residual forces have tendency to attract the particle which comes in contact with the surface. There are 2 types of adsorption. We can classify it into physisorption and chemisorption. Physisorption is an adsorption process which involves physical bonding between the adsorbate with the adsorbent due weaker interaction involving polarization rather than electron transfer. Chemisorption is an adsorption process involving the formation of chemical bonding between the adsorbate and the adsorbent and it requires activation energy. In this video we will introduce the phenomena of adsorption by activated charcoal. Activated charcoal also known as activated carbon is a form of carbon which has been activated either through physical reactivation or chemical reactivation. The surface of activated charcoal exhibits remarkably low reactivity and therefore favours physisorption. Activated carbon has high micro-porosity which significantly provides a high surface area available for adsorption. Due to this property, an activated charcoal has a larger capacity for adsorption and can attract gas particle more effectively than a normal charcoal. Thus, it can be used to remove odours and smoke. The process of adsorption of gas particle on activated charcoal is a spontaneous reaction. However, this adsorption process is fairly slow and a certain time is required for the adsorption process to show visible results. Gas particles lose their momentum, hence possess a low energy level, resulting in being trapped on the surface of activated charcoal as they don’t have enough energy to break the interaction forces between particles and the surfaces. Hence, it can be observed that the smoke and odours can be eliminated by activated charcoal for a period of time. The principle of adsorption is utilized in the recovery of high-purity nitrogen from a supply of compressed air using Pressure swing adsorption (PSA) technique. The adsorption nitrogen generator contains CMS (carbon molecular sieves) – a porous carbon systematic adsorbent which is selective to oxygen in compressed air. Oxygen molecules are separated from the compressed air content in a very short time, and released to the atmosphere upon depressurizing, leaving a high-purity nitrogen. The principle of adsorption is also applied in the water treatment industries. In the water softening process, ion-exchange resins are used to replace magnesium and calcium ions found in hard water with sodium ions. These resins contain sodium ions at its active sites. Upon contacting with the hard water, the magnesium and calcium ions will migrate out of solution and bind to the active site on the resin, replaced in solution by sodium ions.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Ion_exchange Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic "ion exchangers". Typical ion exchangers are ion-exchange resins (functionalized porous or gel polymer), zeolites, montmorillonite, clay, and soil humus. Ion exchangers are either cation exchangers, which exchange positively charged ions (cations), or anion exchangers, which exchange negatively charged ions (anions). There are also amphoteric exchangers that are able to exchange both cations and anions simultaneously. However, the simultaneous exchange of cations and anions can be more efficiently performed in mixed beds, which contain a mixture of anion- and cation-exchange resins, or passing the treated solution through several different ion-exchange materials. Ion exchanges can be unselective or have binding preferences for certain ions or classes of ions, depending on their chemical structure. This can be dependent on the size of the ions, their charge, or their structure. Typical examples of ions that can bind to ion exchangers are: - H+ (proton) and OH− (hydroxide). - Singly charged monatomic ions like Na+, K+, and Cl−. - Doubly charged monatomic ions like Ca2+ and Mg2+. - Polyatomic inorganic ions like SO42− and PO43−. - Organic bases, usually molecules containing the amine functional group −NR2H+. - Organic acids, often molecules containing −COO− (carboxylic acid) functional groups. - Biomolecules that can be ionized: amino acids, peptides, proteins, etc. Along with absorption and adsorption, ion exchange is a form of sorption. Ion exchange is a reversible process, and the ion exchanger can be regenerated or loaded with desirable ions by washing with an excess of these ions... Ion exchange is widely used in the food and beverage industry, hydrometallurgy, metals finishing, chemical, petrochemical and pharmaceutical technology, sugar and sweetener production, ground- and potable-water treatment, nuclear, softening and industrial water treatment, semiconductor, power, and a host of other industries. A typical example of application is preparation of high-purity water for power engineering, electronic and nuclear industries; i.e. polymeric or mineralic insoluble ion exchangers are widely used for water softening, water purification, water decontamination, etc. Ion exchange is a method widely used in household (laundry detergents and water filters) to produce soft water. This is accomplished by exchanging calcium Ca2+ and magnesium Mg2+ cations against Na+ or H+ cations (see water softening)... Industrial and analytical ion-exchange chromatography is another area to be mentioned... An important area of the application is extraction and purification of biologically produced substances such as proteins (amino acids) and DNA/RNA. Ion-exchange processes are used to separate and purify metals... A very important case is the PUREX process (plutonium-uranium extraction process), which is used to separate the plutonium and the uranium from the spent fuel products from a nuclear reactor, and to be able to dispose of the waste products. Then, the plutonium and uranium are available for making nuclear-energy materials, such as new reactor fuel and nuclear weapons... Water softeners are usually regenerated with brine containing 10% sodium chloride. Aside from the soluble chloride salts of divalent cations removed from the softened water, softener regeneration wastewater contains the unused 50 – 70% of the sodium chloride regeneration flushing brine required to reverse ion-exchange resin equilibria. Deionizing resin regeneration with sulfuric acid and sodium hydroxide is approximately 20–40% efficient. Neutralized deionizer regeneration wastewater contains all of the removed ions plus 2.5–5 times their equivalent concentration as sodium sulfate...

Not all soils are created equal. Chemistry helps agriculture succeed in a variety of environments. This video explains how soils (often negatively charged) interact with nutrients (often positively charged) through cation exchange. The cation exchange capacity (CEC) of a soil determines how frequently and in what doses it should receive fertilizer. © 2016, NMSU Board of Regents.

This video lecture talks about Ion exchange chromatography in Hindi, Ion Exchange chromatography, cation exchange chromatography, anion exchange chromatography, ion exchange chromatography practicle, lab procedure, PI of Protein, Zwitter ion, Ph of buffer solution in ion exchange chromatography. Ion exchange chromatogram This lecture explains about the instrumentation, principle of Ion exchange Chromatography. Ion chromatography is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids. However, ion chromatography must be done in conditions that are one unit away from the isoelectric point of a protein.The two types of ion chromatography are anion-exchange and cation-exchange. Cation-exchange chromatography is used when the molecule of interest is positively charged. The molecule is positively charged because the pH for chromatography is less than the pI. In this type of chromatography, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. Anion-exchange chromatography is when the stationary phase is positively charged and negatively charged molecules (meaning that pH for chromatography is greater than the pI) are loaded to be attracted to it.It is often used in protein purification, water analysis, and quality control. The water-soluble and charged molecules such as proteins, amino acids, and peptides bind to moieties which are oppositely charged by forming ionic bonds to the insoluble stationary phase.The equilibrated stationary phase consists of an ionizable functional group where the targeted molecules of a mixture to be separated and quantified can bind while passing through the column—a cationic stationary phase is used to separate anions and an anionic stationary phase is used to separate cations. Cation exchange chromatography is used when the desired molecules to separate are cations and anion exchange chromatography is used to separate anions.

The principle of Ion exchange chromatography is based on the attraction of oppositely charged particle. Many of the biological compounds such as protein, amino acid have charges. These charges can be used in the separation of the compounds by using ion exchanger. The Exchangers are Anionic exchanger which are positively charged and Cationic exchanger which are negatively charged.

Bio-Chem Zorb is composed of two organic scavenger resins and two ion-exchange resins, combined with a high-porosity activated carbon. Together, they remove synthetic chemicals, naturally occurring organic pollutants and metabolic by-products from aquarium water. Bio-Chem Zorb filters water to a level not achievable with carbon alone. Organic Pollutants in the Aquarium: Bacterial decomposition of dead fish and plants, uneaten fish food and solid waste from fish and invertebrates creates organic pollutants in the aquarium. In nature, water currents and tides carry these pollutants away. Aquarium water, however, is changed only periodically. In between changes, organic pollutants can accumulate to harmful levels. Effect of Accumulated Organic Pollutants in the Aquarium: The accumulation of organic pollutants creates a stressful environment and provides a breeding ground for fish pathogens. Some naturally occurring bacteria break down certain organic pollutants. However, this action is often incomplete in an aquarium and uses up oxygen, reducing the amount of oxygen available for fish, invertebrates and the biological filter. Poor water quality ultimately causes suppression of the immune system, leading to disease outbreaks and inhibiting the growth and reproduction of fish and invertebrates. The accumulation of organic pollutants also leads to negative effects such as decreased pH, discolored water, reduced light transmittance and foul odors. Bio-Chem Zorb cleans aquarium water through ion exchange, adsorption and absorption processes. Organic pollutants, toxic heavy metals and aquarium medications are efficiently "sorbed" by organic scavenger resins and high-porosity activated carbon in Bio-Chem Zorb. Using Bio-Chem Zorb In Salt Water: Bio-Chem Zorb is especially useful in removing refractory organics or "yellow water" that form when organic pollutants are not biodegraded. These organic pollutants can reduce the transmittance of light energy necessary for many saltwater invertebrates. With Bio-Chem Zorb, a high redox potential will be easier to maintain. Bio-Chem Zorb is also very effective for removing aquarium medications and treatments. http://www.marinedepot.com/Aquarium_Pharmaceuticals_Bio_Chem_Zorb_10oz_Carbon_Chemical_Filter_Media-Aquarium_Pharmaceuticals_API_MARS_Fishcare-AP2182-FIFMCHCM-AP2181-vi.html

Activated Carbon: Activated carbon, also called activated charcoal, or activated coal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes substituted with active. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m2 (5,400 sq ft), as determined by gas adsorption. An activation level sufficient for useful application may be attained solely from high surface area; however, further chemical treatment often enhances adsorption properties. High exchange Resin: An ion-exchange resin or ion-exchange polymer is an insoluble matrix (or support structure) normally in the form of small (0.5-1 mm diameter) beads, usually white or yellowish, fabricated from an organic polymer substrate. The beads are typically porous, providing a high surface area. The trapping of ions occurs with the accompanying releasing of other ions; thus the process is called ion-exchange. There are multiple types of ion-exchange resin. Most commercial resins are made of polystyrene sulfonate.

What is Filtration •Filtration is a mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained, but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness). Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.Filtration, as a physical operation is very important in chemistry for the separation of materials of different chemical composition. A solvent is chosen which dissolves one component, while not dissolving the other. By dissolving the mixture in the chosen solvent, one component will go into the solution and pass through the filter, while the other will be retained. This is one of the most important techniques used by chemists to purify compounds.Filtration is also important and widely used as one of the unit operations of chemical engineering. It may be simultaneously combined with other unit operations to process the feed stream, as in the biofilter, which is a combined filter and biological digestion deviceFiltration differs from sieving, where separation occurs at a single perforated layer (a sieve). In sieving, particles that are too big to pass through the holes of the sieve are retained (see particle size distribution). In filtration, a multilayer lattice retains those particles that are unable to follow the tortuous channels of the filter. Oversize particles may form a cake layer on top of the filter and may also block the filter lattice, preventing the fluid phase from crossing the filter (blinding). Commercially, the term filter is applied to membranes where the separation lattice is so thin that the surface becomes the main zone of particle separation, even though these products might be described as sieves.Filtration differs from adsorption, where it is not the physical size of particles that causes separation but the effects of surface charge. Some adsorption devices containing activated charcoal and ion exchange resin are commercially called filters, although filtration is not their principal function.Filtration differs from removal of magnetic contaminants from fluids with magnets (typically lubrication oil, coolants and fuel oils), because there is no filter medium. Commercial devices called "magnetic filters" are sold, but the name reflects their use, not their mode of operation.
