用电化学的方法研究了金在硫代硫酸盐介质中溶解的活化机理,指出在金表面形成氧化物是溶解钝化的原因。在有S~(2-),将别是Tl(Ⅰ)存在下作为催化活化剂可加速金的溶解作用,后者甚至可与氰化法相当。
The activation mechanism of gold dissolution in thiosulfate medium was studied electrochemically. It was pointed out that the formation of oxide on gold surface was the cause of dissolution and passivation. In S ~ (2-), Tl (I) will be the presence of catalytic activator can accelerate the dissolution of gold, the latter even with cyanidation comparable.
