Аннотация: Some regularities are studied for the ion-exchange extraction of the gold(I) thiocyanate complexes by ion-exchangers of various physical and chemical structure. It is shown that gold is present in the resin phase as a [Au(SCN)2]- species and is held by the positively charged sorbent functional groups. The conclusion is drawn that hПоказать полностьюigh ion-exchanger affinity for this ion is caused by the high polarizability, linear structure, and small charge of the latter.
