摘要：

The extraction behavior of In3+ into ionic liquids, [C(n)Mim][T(f)2N], was investigated with trioctylphosphine oxide (TOPO) as the extractant and compared with that of a conventional organic solvent system. In the n-dodecane system, the extractability of In3+ increased with increasing hydrochloric acid concentration in the feed aqueous phase. On the contrary when using ionic liquids, In3+ was more extracted at lower concentrations of hydrochloric acid. The contrast between the two systems is probably due to the difference in their extraction mechanisms. Extraction and separation properties of In3+ from Sn4+ Fe3+ and Al3+ were also examined. Indium was quantitatively extracted into the ionic liquid phase and the separation efficiency from other metal ions, especially from Fe3+ was enhanced compared with that in the organic solvent system .
