摘要
本研究从萃取剂浓度、萃取温度、料液酸度、相比、萃取时间及萃取剂的饱和容量和选择性几个方面对新型萃取剂A-408的萃取性能进行了初步研究,并通过正交实验得到了其萃取最佳工艺条件。在最佳条件下,A-408对金(Ⅲ)的单级萃取率大于99.62％。
The function of new extractor A-408 is researched in extractor concentra tion, extraction temp., acidity of aq.,phase ratio,extraction time, saturating capacity and selectivity. At last, the optimum technological conditions of extraction have been obtained by doing right-cross experiment. On these conditions, one-step percentage extraction of Au(Ⅲ)by A-408 is more than 99.62%.
