摘要: 目前采用二(2-乙基己基)磷酸(D2EHPA)从硫酸溶液中萃取铟在生产上虽获得广泛应用,但反萃取又转入盐酸体系,腐蚀刺激性较强.改用D2EHMTPA萃取铟可能较好,有关这方面的研究至今尚未见报道,本文从硫酸溶液中考察了D2EHMTPA萃取铟的性能,并与D2-EHPA和二(2-乙基己基)二硫代磷酸(D2EHDTPA)作比较,以了解这类萃取剂结构上的差别对萃取铟的影响,这对选择及合成高效能萃取剂分子也是有意义的,还应用斜率法、饱和法确定了萃取平衡反应及萃合物组成,根据IR与NMR探讨了D2EHMTPA萃取铟的机理。

Abstract: The extraction behavior of indium with di(2-ethylhexyl) monothiophosphoric acid (D2EHMTPA) was studied. Indium in lower acid concentration (0. 005 mol/L) and backextraction in higher acid concentration (3 mol/L) was extracted. The backextraction is easier than that of D2EHPA and D2EHDTPA. The extraction mechanism was shown by IR and.NMR spectra.
