| 摘 要： | 报道了几种常用的萃取剂从盐酸溶液中革取In3~+的性能分析。发现在较高的盐酸浓度下,N235、TBP萃取In~(3+)的能力均较大,分配比达到最大时所对应的盐酸浓度随萃取剂浓度的增加而减小。初步探讨了N263-MIBK,N235-MIBK,N235-N263从盐酸溶液中苹取In~(3+)时的协同作用,发现对In~(3+)均有明显的协同效应。对于N263-MIBK,协萃分配比在N263和MIBK的浓度分别为0.08 mol/L,4.8 mol/L时达到最大,最大值为580。改变盐酸浓度和温度,协萃分配比亦有较大的变化,但协萃比变化不大。在盐酸浓度为4.5mol/L时,协萃分配比达到最大。

| Abstract: | The present paper is to report the extraction of In~(3+) from hydrochloric acid solution by several extractants. It is discovered that the extraction ability of Alamine 336, Aliquat 336 and TBP for In~(3+) is better in higher concentrations of hydrochloric acid. Synergistic extraction of In~(3+) from HCl solution by Alamine 336 - MIBK, Aliquat 336 - MIBK and Alamine 336 -Aliquat 336 was discussed. The effects of concentration of HCl and temperature on synergistic extraction of In~(3+) by Aliquat 336 - MIBK were studied. |
