| 摘 要： | 为从含有Li和Mg的水溶液中选择性地萃取Li,在FeCl3存在的条件下,以磷酸三丁酯(TBP)为萃取剂,以煤油为稀释剂,在萃取平衡时出现第3相的情况下研究了有机相中Li和Fe的浓度,结果表明萃合物主要集中在中间有机相.针对萃取过程中的分相问题,以TBP为萃取剂,比较了甲基异丁基酮(MIBK)、乙酸乙酯和煤油作为稀释剂对...

| Abstract: | The lithium distribution in the organic phases was studied when the third phase was formed in the extraction of lithium with tributyl phosphate(TBP) diluted by kerosene from the solutions containing lithium and magnesium in the presence of FeCl3.It indicates that lithium is mainly uploaded by the middle organic phase.To avoid the formation of the third phase,different diluents were compared when TBP was used as the extractant,and it shows that TBP diluted by methyl-isobutyl ketone(MIBK) presents a good extr... |
