研究了 P2 0 4、P50 7、Cyanex 92 3及 P2 0 4单一体系与 3种中性有机磷萃取剂 (Cyanex 92 3、TRPO、TBP)组成的混合体系对 In( )、Fe( )的萃取和反萃性能 .发现在 P2 0 4中加入 Cyanex92 3使 In( )的萃取率略有下降 ,反萃率提高 .红外光谱分析证明 P2 0 4与 Cyanex 92 3存在缔合作用 ,抑制 P2 0 4与 In( )和 Fe( )的离子交换反应 ,可以提高过程的反萃率 .
The extraction of In (), Fe () by a mixed system consisting of P2 0 4, P 50 7, Cyanex 92 3 and P2 0 4 and three kinds of neutral organic phosphorus extractants (Cyanex 92 3, TRPO, TBP) The results showed that the extraction rate of In () decreased slightly and the stripping efficiency increased when Cyanex92 3 was added to P2 0 4. Infrared spectroscopy proved that P2 0 4 and Cyanex 92 3 had an associating effect and inhibited P2 0 4 Ion exchange reactions with In () and Fe () can increase the stripping efficiency of the process.
