Аннотация: The problem of simultaneous ion-exchange recovery of platinum(II,IV), rhodium(III), and Ni(II) and their subsequent separation by means of elution was investigated with macroporous anion exchangers Purolite S985 (complex-forming resin) and Purolite A500 (strong basic resin). It was shown that sorption properties of the former sorbent compare favorably with the latter sorbent during recovery from chloride and sulfate-chloride solutions, freshly prepared or stored over three months. The composition of solutions, concentrations, acidity, and storage time were close to industrial solutions obtained at utilization of spent catalysts. A technological scheme for the separation of recovered noble metals and nickel on anion exchanger Purolite S985 by means of elution with 2 M NH4 SCN and 2 M HCl was proposed.
