| Abstract: | The discharge of spent acidic etchant is getting greater than before because of the increase in out put of printed circuit boards with fine lines and many layers.This paper briefly introduced the principle of membrane electrolytic regeneration for the spent acidic etchant,and the pilot experiment was carried out.Base on experiment results,the economic and technical comparison of different regeneration methods was analyzed.The results showed that when the cell voltage was 5 V and electrolyzing time was 2 h,t... |
