Abstract: The extraction of formic acid in the waste water was investigated with N235 ethyl benzene and kerosene. The removal rate of acid through three extractions was up to 96%. Through cubical extraction, the extraction ratio of acid is up to 96%. Then the rest water was treated with the activated carbon. The rest acids are removed from the extraction phase by anti-extraction, the value of COD decreased to the level for biochemical treatment.

摘要: 研究了叔胺N235、乙苯和煤油组成的混合萃取剂萃取含羧酸工业废水。实验结果表明,经三级萃取
酸的萃取率达96%以上,萃取相经精馏使甲酸与萃取剂分离回收,其它的酸经稀碱反萃分离,使萃取剂再生重复使
用;萃余液进一步经活性碳吸附后,COD降到可进入生化池处理。

关键词: 萃取 , N235 , 甲酸 , COD
