摘　　要：本文对二甲硫醚——磺化煤油溶液从盐酸介质中萃取金(Ⅲ)进行系统研究,对影响萃取率的主要因素,如萃取剂浓度、水相酸度、相比、相平衡时间、萃取容量、常见金属离子的影响等进行了探讨.The extraction of Au(III) from a medium of HC1 with dimethyl sulfide(DMS) in sulfonated kerosene has been studied. Factors that influence extraction rate, such as extractor concentration, acidity of water phase, phase ratio, extraction time, extraction capacity etc. are investigated in this paper. Under optimal conditions, the one-step extraction percentage of Au (III) with DMS is more than 98.98%, and the back-extraction percentage by one step is ca. 93.2%.
