研究AgCl-CS(NH_2)_2-H_2O三元体系,对于用硫脲溶解、分离角银矿(AgCl)中的金、银显然是有意义的.但有关该三元体系的文献很少.等结合折光指数认为在AgCl-CS(NH_2)_2-KCl-H_2O系统中只生成配合物Ag[CS(NH_2)]_2Cl.我们的研究工作也证明可生成Ag[Cs(NH_2)_2]_2Cl.我们研究了AgCl-CS(NH_2)_2-H_2O三元体系在20℃及30℃时的溶度和折光指数.由于两个温度的溶度图图形基本相仿,故本文只报道30℃的工作.
Studying AgCl-CS (NH_2) _2-H_2O ternary system is obviously meaningful for the separation of gold and silver from AgCl with thiourea dissolution, but there is little literature about this ternary system. Combined with the refractive index, only Ag [CS (NH_2)] _2Cl was formed in AgCl-CS (NH_2) _2-KCl-H_2O system. Our work also proved that Ag [Cs (NH_2) _2] _2Cl The solubility and refractive index of AgCl-CS (NH_2) _2-H_2O ternary system at 20 ℃ and 30 ℃ were studied. Since the solubility diagrams of the two temperatures are basically the same, this paper only reports the work of 30 ℃.
