研究表明,在酸性介质中,亚砜萃取Pt(Ⅳ)的主要机理为酸性缔合,其萃合物组成为H_2PtCl_6·6H_2O·2PSO。并计算了亚砜萃取Pt(Ⅳ)的萃取平衡常数。
The results show that the main mechanism of the sulfoxide extraction of Pt (Ⅳ) is acidic association in acidic medium, and the complex is composed of H_2PtCl_6 · 6H_2O · 2PSO. The extraction equilibrium constants of sulfoxide extracted Pt (Ⅳ) were calculated.
