摘要
研究了阳离子型表面活性剂改性剂惰性稀释剂Au(CN) -2 萃金体系中各种改性剂对萃取金性能的影响。试验结果表明 :改性剂对萃金的助萃效果与它们的碱性强弱顺序一致 ,即与它们的给电子能力的顺序一致 ,为TAPO >TBP >MIBK >ROH >BIOSO。改性剂的加入避免了体系中第三相的形成 ,使得Au(CN) -2
The effects of modifiers on gold extraction have been investigated systematically for cation surfactant modifier diluent Au(CN) - 2 extraction system. The results show that the gold assistant extraction effects of the modifiers accord with their basicity order, that is the order of their forwarding electrons: TAPO>TBP>MIBK>ROH>BIOSO. The addition of modifier into the extraction system prevents the formation of the third phase in the extraction system. [
