Sorbenty na bázi huminových látek a chitosanu
Klíčová slova:huminové látky, lignit, oxihumolit, chitosan, sorpce
Inexpensive regenerable natural sorbents of toxic metals and radionuclides with high capacity, good mechanical properties and stability have been developed. They are used in waste water treatment, groundwater remediation and in construction of active geochemical barriers. The review deals with sorption properties of humic substances and chitosan as sorbents, which can be used either separately or combined, with enhanced sorption capacity and operation conditions. Sorption studies on chitosan-doped lignite and oxihumolite sorbents are presented.
