摘　　要：铜电解液净化除杂问题一直是电解过程面临的一个难题,杂质含量高的电解液会影响电解铜的质量。工业上目前净化铜电解液的方法都在电积法的基础上改进,这些方法包括间断脱铜砷法、连续脱铜砷电积法、并联循环连续电积法、周期反向电流电积法、极限电流密度法、控制阴极电势法和旋流电积法等。本文通过比较常用的几种电积法的优缺点,对未来净化工艺进行进一步展望。The problem of copper electrolyte purification and impurity removal has always been a difficult problem in the electrolytic process. An electrolyte with a high content of impurities will affect the quality of electrolytic copper.The current methods of purifying copper electrolyte in industry are improved on the basis of electrowinning method.These methods include intermittent copper removal arsenic method,continuous copper removal arsenic electrodeposition method,parallel cycle continuous electrodeposition method,and periodic reverse current electrodeposition method,limiting current density method,controlled cathode potential method,and swirl current product method. By comparing the advantages and disadvantages of several commonly used electrodeposition methods,the future purification process was further prospected.
