自Erlenmeyer等用8-羟基喹啉于柱式层析后,Reeves等和永井等研究某些常見元素的8-羟基喹啉的紙分配层析;Laskowski等以浸有8-羟基喹啉的滤紙分离某些常見离子。但有关貴金属元素的8-羟基喹啉的紙层析行为,文献中似尚缺。本文以异丁醇-乙醇-水-乙酸体系作展开剂,研究在8-羟基喹啉存在下鉑族元素以及銀和金的纸层析行为,找出分离钯-钌-铑-金和钯-钌-铂铱-金等四和五元混合物的合适条件。
Since Erlenmeyer et al. Used 8-hydroxyquinoline in column chromatography, Reeves et al. And Nagai et al. Studied the paper distribution chromatography of 8-hydroxyquinoline, which is a common element. Laskowski et al. Separation of some common ions. However, the paper chromatography behavior of 8-hydroxyquinoline, which is a precious metal element, seems to be lacking in the literature. In this paper, an isobutanol-ethanol-water-acetic acid system was used as a developing solvent to study the chromatographic behavior of platinum group elements and silver and gold in the presence of 8-hydroxyquinoline. The separation of palladium-ruthenium-rhodium-gold and palladium - Ruthenium - platinum iridium - gold and other four and five yuan mixture of the appropriate conditions.
