剂已有若干报道,但未见用于分析化学和其他元素的萃取。本文研究用甲苯为稀释剂,P_(350)为萃取剂,考查对镓的萃取行为、盐析剂效应、络合物组成及其从Al、Fe、Zn、Ni、Cd等中分离的可能性。结果表明,P_(350)是萃取分离镓的良好萃取剂,微量镓可从大量Al、Ni、Fe、Tl、In、Cd等中分离,结合罗丹明B法,用于铝土矿、煤矸石和铝中镓的萃取分离获得良好结果。
There are several reports of agents, but no extraction for analytical chemistry and other elements. In this paper, the extraction behavior of gallium, the effect of salting-out agent, the composition of complex and the possibility of its separation from Al, Fe, Zn, Ni and Cd were investigated using toluene as diluent and P_ (350) as extractant . The results show that P_ (350) is a good extractant for the extraction and separation of gallium. The trace gallium can be separated from a large amount of Al, Ni, Fe, Tl, In and Cd, Good results have been obtained with the extraction of gallium from aluminum.
