摘要
研究了蛇纹石中钯的萃取的有效方法 ,报道了蛇纹石浸出液萃取条件选择及萃取物还原实验。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pH值为 1,萃取时间为 3 0min ,用分光光度法测定钯的提取率达 98%。
An useful method on extracting palladium from serpentine, and the experiment on the condition of extracting palladium from serpentine and the reduction of extraction were studied. Using di-(2-ethylhexyl)-dithiophosphoric acid (D 2EHDTPA) as the extractant in hydrochloric acid medium, the pH of the extracting liquid is 1 and the extracting time is 30 min, the recovery of palladium reached 98% determined by spectrophotometry.
