摘要： 迄今,国内外萃取回收铊的工艺都是以三价形式进行的,这不论在经济上还是在技术上都不如萃取一价铊优越。国外已有人对用二-(2-乙基已基)二硫代磷酸(下文以D2EHDTPA或HA代之)从水溶液中萃取Tl+进行了研究。为了更好地了解D2EHDTPA萃取TI+的行为,我们也对D2EHDTPA萃取Tl+进行了研究。

Abstract: The extraction of Tl+ from sulfuric acid solution withdi-2-ethylhexyldithiophoric acid (D2EHDTPA) has been studied.The experimental conditions of the effect of the solution acidity and the lime needes on attaining equilibrium have been found.The composition of the extracted complex has been determined by the methods of saturation and molecular ratio.The structure of the extracted complex has been discussed on the basis of iis IR and NMR.The extracting reaction is process of thecation exchange.
