摘　　要：主要研究了从锇铱矿的锇钌蒸残液中通过刚果红离子缔合型负载形成树脂分离贵贱金属的条件。此种研究尚未见报道.于 pH1.0的盐酸介质中,缔合吸附于刚果红负载形成树脂上的 Au,Pd,Pt,Rh 用 pH1.0的5%的硫脲-HCI 洗脱剂洗脱,回收率均在96%～104%。此酸度下大量贱金属以阳离子存在不被吸附而流出除去.残留于柱上的少数少量贱金属可用 pH1.0的 HCI 淋洗除去.通过于锇铱矿的锇钌蒸残液中加标准回收实验和方法检验,获得满意结果,RSD 在1.22%～3.32%之间。The conditions of separation of noble metals from residual solution of Os and Ru of the osmiridium with congo red associate forming resin have been studied.Up to now the method is not reported.The recovery of five noble metals, Au,Pd,Pt,Ir and Rh in pH1.0 HCl medium is 96%-104%.Most base metals in cations are not adsorbed and removed. A small number of residual base metals on column are eluted with pH1.0 HCl solutiom.It can be used to separate and enrich noble metals in copper-nickel mineral and dectrolytic copper anode mud.The results are satisfactory.
