| 摘 要： | 膦氧化物萃取剂Cyanex 921和Cyanex 923用于从金的氰化物溶液中萃取Au(CN)2-,反应可在常温下进行;煤油作稀释剂,锂盐作盐析剂,能明显提高萃取率;萃取反应在3 min即可达到平衡;Cyanex 921和Cyanex923的萃取效果相近.在60℃时,KCN水溶液能将萃入有机相的Au(CN)2-完全反萃取出来.

| Abstract: | This experiment deals with the equivalent extraction efficiency of gold and the relation between the variables such as time temperature,ionic strength, Au(CN) - 2 concentration in aqueous solutions, organic solutions and extractant concentration in organic solution when gold(i) is extraction from cyanide solutions by phosphine oxies Cyanex 921 and Cyanex 923. In addition,it involves the counter extraction and the extraction reaction mechanism. |
