摘　　要：碱性蚀刻液的再生循环常采用溶剂萃取—电解还原法。探讨了一种再生老化并报废的萃取剂β-二酮工艺。结果表明:再生萃取剂β-二酮与新配制萃取剂β-二酮在从碱性蚀刻液中萃取铜的性能上无明显差别;该方法简单,处理成本低,实用性强。The process of solvent extraction-electrolytic reduction is usually adopted in the recycling of alkaline etching solution.A regenerating process for the aged and scrapped extractantβ-diketone was proposed.The experimental results show that the performances of the regeneratedβ-diketone for extracting copper from alkaline etching solution is almost same as freshβ-diketone.The approach suggested is simple,economical and practicability.
