摘要
研究了用正-丁基辛基亚砜萃取、S-丁基异硫脲盐反萃金(Ⅲ)的行为.实验结果表明萃合物的组成为H_3O(n-BOSO)_3AuCl_4,反萃金(Ⅲ)是离子交换机理,金(Ⅲ)萃合物用元素分析、热分析、摩尔电导、UV和IR光谱进行了表征。
In this paper, the behavior for extraction and back-extraction of gold (Ⅲ) with n-butyloctyl sulfoxide and s-n-butylisothiouronium have been investigated, respectively. Experimental results showed that the composition of extraction complex is H3O(n-BOSO)3AuCl4 and back-extraction of gold(Ⅲ) is ion exchange machanism. The extraction complex of gold(Ⅲ) has been characterized by element analysis, thermal analysis, molar conductance, UV and IR spectra.
