我们对铂族的氯络合物体系曾进行了较系统的研究。考虑到硫氰酸盐是无机分析中的一种重要络合剂,Martin、Locke 和 Lederer 曾在硫氰酸存在下应用不同有机溶剂进行纸上层析分离若干普通和希有元素。Kertes 及其合作者也曾用4-甲基戊酮等在硫氰酸体系中研究了包括金、铂(Ⅱ)、钯在内的近40种元素的纸上层析行为,但作者对锇和铑未列举数据,铂(Ⅱ)、钯和金的分离也未尽完善。Berg 等以非挥发性铂族的硫氰酸络合物与
We have conducted a more systematic study of the platinum-based chloride complex system. Considering that thiocyanate is an important complexing agent in inorganic analysis, Martin, Locke, and Lederer used several organic solvents in the presence of thiocyanate to separate several common and desirable elements by paper chromatography. Kertes and his collaborators have also investigated the chromatographic behavior of nearly 40 elements including gold, platinum (II), palladium in thiocyanate systems using 4-methylpentanone and the like. However, And rhodium are not listed data, platinum (Ⅱ), palladium and gold separation is not perfect. Berg and other non-volatile platinum group thiocyanate complexes with
