研究了2-乙基己基膦酸单(2-乙基己基)酯(简称P507)从硫酸体系中萃取铟的机理,确定了萃合物的组成,并用红外光谱确证。同时对铟的萃取条件及负载有机相的反萃条件进行了筛选。
The mechanism of extracting indium from sulfuric acid by 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (P507) was studied. The composition of the complex was determined and confirmed by infrared spectroscopy. At the same time, the extraction conditions of indium and the stripping conditions of loaded organic phase were screened.
