本文采用二(2—乙基己基)磷酸(简称P_(204))从硫酸体系中萃取铟。确定了其萃取机理及萃合物组成,并用红外光谱确证。测定出表观萃取平衡常数,并对铟的萃取条件进行筛选。
In this paper, di (2-ethylhexyl) phosphoric acid (P_ (204)) was used to extract indium from sulfuric acid system. The extraction mechanism and the composition of the extract were confirmed and confirmed by FTIR. The apparent equilibrium constant of extraction was determined, and the extraction conditions of indium were screened.
