Abstract: A method of reproduction,reclamation and cyclic utilization of devil liguor of copper passivation-membrane electrolysis method was presented.This method integrate electrolysis with membrane spration technology,which can be used to tream several liqud,such as chromium plating,copper passivation devil liguor,stripping solution and the roughening solution of plastics electroplating and so on.The selectionof procedure principl of reproduction reclamation,detemination of technologycal process and so on were discussed in this paper.
