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 sorbeПоказать полностьюnt 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.
