Platinum has been widely applied in catalytic industry and the recovery of noble metals from industrial wastes becomes an economic issue. The laboratory studies of platinum(IV) microquantities removal from 1M aluminium, copper, iron, nickel and zinc chloride solutions in 0.1M hydrochloric acid solutions on the anion exchanger Duolite S 37 of the functional secondary and tertiary amine groups were carried out. For this anion exchanger the fraction extracted values (%E, Pt(IV)) as well as the sorption isotherms were determined depending on the kind of aqueous phase and phase contact time. Moreover, the bed and weight distribution coefficients as well as working and total ion-exchange capacities were calculated from the platinum(IV) breakthrough curves. Kinetic parameters were determined.
铂已广泛应用于催化工业，从工业废料中回收贵金属成为一个经济问题。开展了在0.1M盐酸溶液中，利用具有仲胺和叔胺官能团的阴离子交换树脂Duolite S 37从1M氯化铝、氯化铜、氯化铁、氯化镍和氯化锌溶液中去除微量铂(IV)的实验室研究。对于这种阴离子交换树脂，根据水相种类和相接触时间测定了萃取率（%E，Pt(IV)）以及吸附等温线。此外，根据铂(IV)穿透曲线计算了床层和重量分配系数以及工作和总离子交换容量。测定了动力学参数。
