| 摘要: 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P350和TBP相比较,萃取能力大小顺序为:TOPO>P350>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)⇔HInCl4·2TOPO(o)IR和NMR研究证明:铟是以H[InCl4]形式被萃入TOPO有机相中的. |

| Abstract: The extraction behavior of indium with trioctyl phosphine oxide(TOPO)from hydrochloric acid solution have been studied. The extraction percentage of TOPO increases as the hydrochloric acid concentration increases. The extraction capability of three extractants is in the order.TOPO>P350>TBP This is showed by slope method and chemical analysis that the extraction reaction of indium can be expressed as follows: In(a)3++H(a)++4Cl(a)-+2TOPO(o)⇔HInCl4·2TOPO(o) The studies of IR and NMR show that indium is extracted into the TOPO organic phase as species H[InCl4]. |
