| Abstract: | In order to eliminate the pollution of cyanide silver plating solution to the environment,the composition of alow polluted and cyanide free silver plating solution with 5,5-dimethylhydantoin(DMH) and potassium pyrophosphate as complex forming agent was studied.The surface morphology of silver coating was evaluated under different concentration of AgNO3,DMH,K2CO3,potassium pyrophosphate,additive and pH value.The results indicated that bright and fine silver coatings could be obtained in low polluted and cyanide free silver plating solution.And this low polluted and cyanide free silver plating solution has a potential application in electroplating industry because of low pollution to the environment and easy disposing of waste water. |
