【摘要】 本文用循环伏安法研究Ag⁺—NH₃—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（NH₃）₂NS]时阴极析出银的电化学极化最大。更多还原

【Abstract】 The reducing complex ions in the systems of ternary complexes and its corresponding parent complexes are studied by cyclic ac voltametrical method.The iτ1/2-i relation of the discharging reaction is determined also. Experimental result shows that the reducing ions are mixed ligands complex species which are present dominantly in solution. As there is no preceding reaction step in this discharging reaction, the mixed ligand complex species discharge directly. The electrochemical polarization of cathode, on which the silver deposits, is maximum when the reducing ion is [Ag(NH3)2NS].更多还原
