Adsorption has proven, time and time again, to be the most effective and economical process for removing those invisible nuisances from the air you breathe. Drinking h2o should be obtained from natural h2o by treating the natural h2o with a mix of activated carbon and flocculating agent Al OH 3. Adsorption of pesticide imidacloprid as an insecticide from aqeous solution onto granular activated carbon (GAC) under different conditions was studied. Impregnated carbons are also used for the adsorption of H2S and mercaptans. It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject. There is approximately 100 acres of surface area within a pound of a piece of activated carbon. Techniques for removal of colour from waste water include biological treatment, coagulation, floatation, oxidation, hyperfiltration and adsorption. Adsorption of gold complexes (especially ion disianoaurat) on activated carbon is the basis of modern techniques for gold extraction process. The method of removing these particles is called adsorption. Check us out at www.tutorvista.com Adsorption is the adhesion of molecules of gas, liquid, or dissolved solids to a surface. In fact, one teaspoon of activated charcoal has a total surface area as big as a football field! This opens up the charcoal and exposes more of its surfaces, so it can adsorb much more.
