摘要: 本工作研究了二甲庚基乙酰胺(N503)自盐酸溶液中萃取铟的性能,得出其萃取能力随着酸度的增加而增加。经斜率法和化学分析法确定,N503自盐酸溶液中萃取铟的反应为: 萃合物中的溶剂化数n随酸度而变化。IR和NMR研究证明,铟是以HInCl4形式被N503萃入有机相的。在盐酸体系中(HCl<2N),N503对镓、铟、铊的萃取顺序为:Tl(Ⅲ)>Ga(Ⅲ)>In(Ⅲ)

Abstract: The extraction behaviour of indium with dimethylheptyl acetamide from hydroch-loric acid medium has been studied. The extractability is found to increase with the concentration of HCl. It is confirmed by an application of the slope method and chemical analysis that the extraction of In with N503 from hydrochloric acid solution can be represented as follows: The solvation number n of the extracted species varies with the concentration of hydrochloric acid. IR and NMR data show that the indium is extracted in the form of HInCl4 into the organic phase of N503. Under the condition of [HCl]<2N the extract-ability of galliun, Indium and thallium with N503 was found to be in the following order:Tl(Ⅲ)>Ga(Ⅲ)>In(Ⅲ)
