| 摘 要： | 采用D190 型大孔巯基树脂分离富集微量金和钯 ,研究了各种条件对分离富集和测定的影响 ,证明了金和钯在 3 %王水介质中形成氯络阴离子与树脂上的巯基 (-SH)发生螯合作用形成螯合物而迅速地被吸附在树脂上。同时 ,溶液中一些贱金属离子不易与巯基生成螯合物而分离。采用酸性硫脲定量洗脱 ,树脂结构不被破坏 ,可重新使用

| Abstract: | Detemination of Au and Pd with D 190 type sulphydryl resin has been studied, in further, the optimal conditions of separation and preconcentration are summed. The chlorocomplex anion of Au and Pd can be formed easily in 3% aquaregia medium and can be chelated on the sulphydryl of resin. The stable chelate can be adsorbed rapidly on the resin and can be aslo separated from many base metals of solution. While time, acidic thiourea is used as eluting agent.Au and Pd can be eluted quantitatively.The resin can be retreated and reused easily.The results is satisfied by the determination of standard samples. |
