CARBON CRYOGEL AS AN ADSORBENT FOR REMOVAL OF DRUGS AND PESTICIDES FROM WATER

Abstract

Carbon cryogel (CC), obtained by pyrolysis of resorcinol–formaldehyde cryogels, was chemically modified and used for adsorption of drugs and pesticides from water. FTIR analysis and point of zero charge determination showed that applied chemical treatments affect the surface chemistry of carbon cryogel by changing the acidity of the surface as well as the nature and amount of surface oxygen groups. Generally, the chemical modification has no influence on drugs adsorption, while both chemical treatments increase the adsorption of pesticides onto carbon cryogel surface.
