介绍了几种印刷线路板铜蚀刻废液的回用处理工艺(如电解再生法、氧化再生法)及其所用材料(包括电极和萃取剂),概述了几种从铜蚀刻废液中回收资源的方法(如利用碱氨蚀刻废液制备胆矾或氯化亚铜).%Several treatment processes (such as electrolytic regeneration and oxidative regeneration methods) for reuse of spent copper-etching solution from the production of printed circuit board and the materials used (including electrodes and extracting agents) were introduced. Some methods for recovering recourses from spent copper-etching solution, such as using spent alkaline ammonia etching solution to prepare blue vitriol or copper(I) chloride, were described.
