新型含磷无机离子交换剂的研究(Ⅳ)——贵金属元素在焦磷亚硒酸锡上的薄层色谱分离

Studies on New Inorganic Ion Exchanger Containing Phosphorous(Ⅳ)--Thin-Layer Chromatography Separation of Noble Metal Elements on Stannic Selenopyrophosphate

研究了贵金属元素在新型含磷无机离子交换剂--焦磷亚硒酸锡上的薄层色谱分离。探讨了贵金属元素在酸性介质、NH_(3)·H_(2)O-NH_(4)Cl、三甲胺及三甲胺-乙醇展开体系中的变化规律,部分金属离子符合关系式R_(m)=AlogC+B,并分离了一系列二元和三元贵金属元素的混合物。

Thin-layer chromatography of the noble metal elements on the inorganic ion exchanger stannic selenopyrophosphate has been studied systematically.The change regularity of the noble metals elements in the acidity medium,the ammonia-ammonium chloride,the trimethylamine and the trimethylamine-alcohol development systems has been discussed.Partial metal ions obey relationship R_(m)=A log C+B.A series of binary and ternary mixtures of the noble metal elements was separated successfully.
