本文用循环伏安法研究Ag~+—NH_3—NS双络合剂体系及相应的单络合剂体系的放电络离子,并用时间电位法测定了放电反应的iτ~(1/2)—i关系。结果表明:在双络合剂体系中放电的是溶液中主要存在的复合络离子,此放电反应没有前置转化步骤存在,是复合络离子直接放电,当放电离子是[Ag(NH_3)_2NS]时阴极析出银的电化学极化最大。
In this paper, the cyclic voltammetry of Ag ~ + -NH_3-NS double complexing agent system and the corresponding single complex agent discharge complex ions, and measured by time-potential discharge reaction iτ ~ (1/2) -i relationship. The results show that the complex complex ions mainly exist in the solution discharged from the double complexing agent system. The discharge reaction does not exist in the pre-conversion step and is the direct discharge of the complex complex ions. When the discharge ions are [Ag (NH_3) _2NS] Cathodic precipitation of silver electrochemical polarization maximum.
