P204-Cyanex 923混合溶剂萃取铟
摘要:
研究了P204、P507、Cyanex 923及P204单一体系与3种中性有机磷萃取剂(Cyanex 923、TRPO、TBP)组成的混合体系对In (Ⅲ)、Fe (Ⅲ)的萃取和反萃性能.发现在P204中加入Cyanex923使In (Ⅲ)的萃取率略有下降,反萃率提高.红外光谱分析证明P204与Cyanex 923存在缔合作用,抑制P204与In(Ⅲ)和Fe (Ⅲ)的离子交换反应,可以提高过程的反萃率.

Extraction of Indium with Mixture of P204 and Cyanex 923
Abstract:
The extraction and stripping of In(Ⅲ ) and Fe(Ⅲ ) with di(2-ethylhexyl) phosphoric acid (P204), 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (P507), Cyanex 923 (a mixture of trialkyla ted phosphine oxides) and the binary mixtures of P204 with Cyanex 923, trialkyl phosphine oxide (TRPO) and tributyl phosphonate (TBP) at different aqueous acidities have been studied. The extraction yield of In (Ⅲ ) was found slightly decreased, but its stripping yield increased when Cyanex 923 was added to P204. The IR spectrometry was used to elucida te the extractio n mechanism by P204, Cyanex 923, and P204-Cyanex 923 mix ture, loaded indium and iron.
