4-甲基-2-戊酮萃取分离,EDTA络合滴定法测定含铬、铝电镀废水中的铝

Analysis of Aluminum Ion in Electroplating Wastewater with 4-methyl-2-pentanone as Extractant and EDTA Complexometry

针对铝离子和铬化合物共存的电镀废水 ,采用 4 -甲基 - 2 -戊酮作为萃取剂分离六价铬 ,EDTA络合滴定法测定铝含量 ,分析结果令人满意。

Used 4-methyl-2-pentanone as extractant, heavy chromic acid group was extracted in the electroplating wastewater in which aluminum ion and chromium compond coexist. And then aluminum ion was analyzed with EDTA complexometry. The analysis result was satisfying.
