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-萃入有机相。
Abstract: 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.
