摘　　要：为了探讨蛇纹石中钯的浸取与富集的有效方法 ,进行了蛇纹石浸出液萃取条件选择及萃取物还原试验 .在盐酸介质中 ,以二 ( 2 -乙基已基 )二硫代磷酸 ( D2 EHDTPA)为萃取剂 ,浸出液p H为 1,萃取时间为 30 min,钯的提取率达 98%The experiment on the condition of extracting palladium from serpentine and on the reduction of extract was conducted,using di (2 ethylhexyl) dithiophosphoric acid as the extractant in hydrochloric acid medium. The pH of the leaching agent was 1 and the leaching time was 30 min. The extraction rate of palladium reached 98%.
