摘要
采用络合萃取法处理 6 硝基间甲酚废水 ,一次萃取率达到 99 9% ,最佳的萃取条件为 :V(络合剂 )∶V(稀释剂 ) =1∶2 ,萃取油水体积比为 1∶2 ,溶液pH值低于 3。萃取剂可经过反萃再生其效率不变。
Waste water containing 6-nitro-m-cresol was treated by applying complex extraction method with a high extracting efficiency over 99.9%. Optimal extraction conditions were as follows: V(complex agent): V(diluent) = 1:2 in extraction V(oil): V(water) = 1:2, pH value of solution was less than 3. The extracting efficiency of extractor was kept after back-extraction regeneration.
