本文研究了三辛基氧化膦(TOPO)自盐酸溶液中萃取铟的性能,其萃取率是随酸度的增加而增加。与P_(350)和TBP相比较,萃取能力大小顺序为:TOPO>P_(350)>TBP经斜率法和化学分析法研究确定,TOPO白盐酸溶液中萃取铟的反应为:In_((a))~(3+)+H_((a))~++4Cl_((a))~-+2TOPO_((o))F(?)HInCl_4·2TOPO_((o))IR和NMR研究证明:铟是以H[InCl_4]形式被萃入TOPO有机相中的。
In this paper, the extraction of indium from the solution of trioctylphosphine oxide (TOPO) from hydrochloric acid was studied. The extraction rate increased with the increase of acidity. Compared with P_ (350) and TBP, the order of extraction capacity was TOPO> P_ (350)> TBP. The slope reaction and chemical analysis showed that the reaction of extraction of indium in TOPO white hydrochloric acid was: In_ (a) ) ~ (3 +) + H_ (a) ~ ++ 4Cl _ (+ a) ~ - + 2TOPO _ ((o)) F (?) HInCl_4 · 2TOPO _ ((o)) IR and NMR studies have shown that indium Is extracted into the TOPO organic phase as H [InCl_4].
