摘要/Abstract

摘要： 本文研究了双(正-辛基硫醚)乙烷[C₈H₁₇S(CH₂)₂SC₈H₁₇]对钯的萃取;讨论了盐酸浓度、稀释剂对萃取钯的影响;并且通过等克分子系列法、饱和法、Asmus法、固态络合物的化学分析及核磁共振谱,红外光谱的研究,确定了萃合物的组成和结构。

Abstract: In this paper the extraction of palladium with bis (n-octylsulfide) ethane [C₈H₁₇S(CH₂)₂SC₈H₁₇) has been studied. The effect of concentration of hydrochloric acid and diluent has been discussed. It was shown that bis (n-octylsulfide) ethane is highly effective extractant of palladium from hydrochloric acid medium. Compostion of extracted complex was established by method of isomolar series and of saturation, Asmus's me -thod and chemical analysis of solid complex and found to be Pd: bis (n-octylsulfide) ethane = 1:1. Study on the nuclear magnetic resonance spectrum and infrared spectrum indicated that bis (n-octylsulfide) ethane is coordinated to palladium through sulphur to form five-membered neutral chelate complex.
