ANION EXCHANGE RESINS FOR RECOVERY OF ANIONS AND ANIONIC COMPLEXES CONTAINING METALS FROM LIQUIDS AND PULPS

摘要

The present invention relates to a range of anion-exchangers resins (sorbents) suitable for the recovery of anions and anionic complexes containing metals from liquids and/or pulps. The resin is also suitable for selectively separating chemical elements have very similar physical and chemical characteristics, for example, nickel and cobalt. The anion-exchange resin has the structure (I); wherein the ratio of M/N/P/Q is in the ranges of 3.5-6.5/2-4/ 65-80/15-21 and R1 and R2 represent any one of the following groups: R1: -HC2H4NH2;-(C2H4NH2)2;-HC2H4NHC2H4NH2; -H(C2H4NH)2 C2H4NH2;-C2H4NH(C2H4NH-C2H4NH2), R2: -H;-C2H4NH2;-C2H4NH-C2H4NH2.
