摘要
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.
By using a diaphragm cell, the coupled rate between pure Ni_3S_2 and Cu^(2+)/ Cu^+ was studied in the acidic chloride solution. It has been found that Cu_2S is a good material for cathode. The reaction rate of Ni_3S_2 corrosion dissolution is controled by the combined processes of solid diffusion and electron charge transfer.
