The normal function of aqueous chromic electroplating bath, occuring defect on electroplating film, was regenerated by adding aqueous ferrocyanide for precipitating metal waste with decreasing the defact on plated film. Thus, the K4FeCN6.3H2O 20 % W/V soln. was added in the electroplating bath in 7ml/ 1l of electroplating soln., and then maintained for 30min to give electroplating component showing normal function.
