本文通过对平衡电极电位和极限电流密度实验测定值的分析,探讨了在Cu(Ⅰ)～CH_3CN-H_2SO_4-H_2O 体系中 Cu(Ⅰ)络离子主要存在形式和阴极还原机理。实验结果表明了在乙腈过量的情况下,主要存在形式的 Cu(Ⅰ)络离子和在阴极上直接还原的 Cu(Ⅰ)络离子均为 Cu(CH_3CN)_3~+。Cu(CH_3CN)_3~++e→Cu+3CH_3CN
In this paper, the main existing forms and cathodic reduction mechanisms of Cu (Ⅰ) complex ions in Cu (Ⅰ) ~ CH_3CN-H_2SO_4-H_2O system were discussed through the experimental analysis of equilibrium electrode potential and limiting current density. The experimental results show that Cu (Ⅰ) complex ions mainly exist in the presence of acetonitrile and Cu (Ⅰ) complex ions which are directly reduced on the cathode are Cu (CH 3 CN) 3 +. Cu (CH_3CN) _3 ~ + e → Cu + 3CH_3CN
