本文研究了活性硫化镍的性质，分析了镍电解阳极液的组成，对活性硫化镍的除铜[Cu（Ⅱ）]过程进行了动力学实验并对中间产物进行了分析，提出了活性硫化镍的除铜机理：活性硫化镍有较大的比表面积，CuCl2-4不在活性硫化镍表面上作用较快，形成的Ni2+进入了溶液，由CuS于有强的吸附性，在整个除铜过程中CuS的脱附和扩散成为控制步骤．由于活性硫化镍孔结构的存在，这种除铜的扩散控制步骤可能由三维扩散控制经一中间过渡态转为一维扩散控制
In this paper, the properties of active nickel sulfide were studied, the composition of nickel electrolytic anolyte was analyzed, the kinetics of Cu (Ⅱ) removal from activated nickel sulfide was studied, and the intermediate products were analyzed. The copper removal mechanism: active nickel sulfide has a larger specific surface area, CuCl2-4 is not activated nickel sulfide surface faster, the formation of Ni2 + into the solution, by the strong adsorption of CuS in the entire copper removal process CuS desorption and diffusion become the control step. Due to the existence of active nickel sulfide pore structure, this copper-removing diffusion control step may change from three-dimensional diffusion control to one-dimensional diffusion control via an intermediate transition state
