摘　　要：研究了铜电解精炼过程中添加剂工业监控的原理和方法。研究结果表明:阴极过电位是电解液性质的实时反映,通过阴极过电位的工业监控可得出不同电解条件时,添加剂最佳量的控制,从而在复杂铜电解过程中使高纯阴极铜生产的稳定性提高了6%;平均电流效率提高了1%。The principle and method for the industrial controlling of copper electrolysis by means of the cathodic overpotential were described. The industrial results show that the cathodic overpotential is essential to the electrolyte characteristics. Through auto-control of cathodic overpotential, the optimum amount of additives can be determined, the stability of high pure cathodic can be raised by 6%, and the average current efficiency is raised by 1%.
