【摘要】 报道了吐温 (Tween) 80 - (HN4) 2 SO4-水的固液萃取体系中Pt(Ⅳ )、Pd(Ⅱ)、Ir(Ⅳ )碘络阴离子的萃取行为 ,在HCl-NH4I介质中 ,该体系可萃取Pt(Ⅳ)、Pd(Ⅱ)、Ir(Ⅳ ) ,而贱金属不被萃取 ,可用于Pt、Pd、Ir与贱金属的分离。对合成样进行了萃取分离 ,并初步探讨其机理。更多还原

【Abstract】 A new method for the separation of iodine complex anions of Pt,Pd,Ir through liquid-solid extraction system of Tween 80-salt-water was investigated.In the medium of HCl-NH 4I,the proposed method can separate Pt,Pd,Ir and has been used for the separation of Pt,Pd,Ir in the synthetic samples.The mechanism has been studied preliminarily.更多还原
