КОМПЛЕКСООБРАЗУЮЩИЙ СОРБЕНТ И СПОСОБ ЕГО ПОЛУЧЕНИЯ

摘要

The invention relates to applied chemistry, in particular to a complexing sorbent containing an active sorbing layer which is immobilised on a solid carrier embodied in the form of a cellulose or a synthetic polymer and comprises ethylenediamine or diethylenetriamine or triethylenetetramine or tetraethylenepentamine or polyethylenepolyamine or polyethylenepolyamine with copolymers condensed with complexons selected form a group containing carboxyl-containing complexons with fragments NHCH2COOH,-N(CH2COOH)2, compexons with phosphonic groups arrangement N(CH2PO3H2)2, hydroxyl-containing complexons with fragments = NCH2CH2OH, HOCH2CH2-N- CH2COOH, HOCH2CH2-N-CH2PO(OH)2. Methods for producing inventive sorbent and using said sorbent for removing aliovalent ions of different metals and metalloids from aqueous media at a large range of pH associated with a subsequent regeneration of said sorbent are also disclosed.
