摘要：

Resins having two types of ligands: guanidine and aminoguanidine on copolymers of vinylbenzyl chloride (VBC)/ methyl methacrylate (MM)I divinylbenzene (DVB) and on styrene (S)/DVB have been investigated in respect to their selectivity towards dicyanoaurate anions. Resins coded CH and CP displayed high selectivity and sorption of gold from its diluted solution. They sorbed 10 - 11 mg of gold/g and dicyanoaurate distribution coefficient reached 1890 and 2290, respectively. Resins have the following selectivity order when sorption was carried out from solution of 5.08 mg Au/dm(3): resin U-BIS Zn>Ag>Au>Cu; resin CP Au>Zn>>Cu>>Ag; resin CH Au>Zn=Ag>>Cu. Resins have weak affinity towards iron complexes.
