| Abstract: | Spent alkaline etchant is a kind of industrial waste with high concentration of copper and chloride, so its recycling has high economic benefit and environmental benefits. The paper introduces and analyzes two kinds of treatment modes of spent alkaline etchants. On - line mode not only regenerates alkaline etehant but also recovers metallic copper. Off- line mode recovers different cupric salts. Based on the analysis of resources recycling and environmental benefits, on - line mode has important appli- cation prospects. |
