【摘要】 选用ＬＩＸ－５４作为萃取剂从印制板蚀刻废液中回收铜．探讨了萃取系统的一些条件．对含Ｃｕ１０７．３９ｇ／Ｌ和ＮＨ３１２８．４ｇ／Ｌ的蚀刻液，经３级萃取即可达到含Ｃｕ约３０ｇ／Ｌ，并基本不萃氨，萃余液可返回蚀刻液．实验还考察了萃取剂的降解性能．更多还原

【Abstract】 LIX54 was chosen as extraction reagent to treat the spent etching solution for copper recovery. The extraction conditions were investigated. For an etching solution containing Cu 107.39g/L, NH3 128.4g/L, after the processing of 3-stage extraction, the copper content can be reduced to about 30g/L without ammonia extracted, and the raffinate can be favorably recycled to the etching solution. No apparent degradation of the extractant was observed. 更多还原
