摘要/Abstract

摘要： 本文研究了α-正十二烷硫基乙酸乙酯在盐酸和硝酸体系中的R_f图谱,对四十多种金属离子进行反相纸层析,初步确定对钯具有优异的萃取性能,并用液-液萃取法研究了稀释剂和酸度对萃取钯的影响,测定了萃取络合物的组成为PdCl₂·2ELTA,探讨了萃取机理。

Abstract: By means of reversed-phase paper chromatography with ethyl n-iaurylthioace-tate (ELTA) as stational phase, the R_f graph of more than 40 metallic ions was obtained. From the R_f graph it can be found that ELTA is an excellent extrac-tant for Palladium. The extraction of Palladium with ELTA was then studied by the method liquid-liquid extraction. The effects of different diluents and concentrations of hydrochloric acid are discussed. The composition of the extracted complex is PdCl₂(ELTA)₂.The mechanism of the extraction of Palladium by ELTA was also studied.
