利用隔膜电解池研究了Ni_3S_2与Cu~(2+)/Cu~+偶合反应速度,Cu_2S是Ni_3S_2腐蚀溶出良好阴极.Ni_3S_2的腐蚀溶出受固体扩散和电荷传递混合控制,反应活化能为11.596kJ/mol.
The electrochemical reaction between Ni 3 S 2 and Cu 2+ / Cu + was studied by means of a membrane electrolyzer, and Cu 2 S was a good cathode for the dissolution of Ni 3 S 2. The corrosion dissolution of Ni 3 S 2 was controlled by the combination of solid diffusion and charge transfer. The activation energy was 11.596 kJ / mol.
