摘要
研究了以三正辛胺、仲辛醇和磷酸三丁酯为载体,Span80为表面活性剂,正丁醇为助表面活性剂,煤油为膜溶剂制成的微乳状液膜分离Cr(Ⅵ)。通过正交试验确定了微乳状液膜萃取Cr(Ⅵ)的最佳方案。此最佳条件下Cr(Ⅵ)的萃取率达99.77%。
The Cr ( VI ) was extracted by microemulsion liquid membranes. The tributyl phosphate(TBP) ,secondary octyl al-coho ,triotylamine (TOA) were used as carriers, Span80 as the surfactant, kerosene as solvent and n -butyl alcohol as co -surfac- tant. The system was used in separating and determining of trace chromium ( VI ) from leather waster water. The optimal condition was obtained and the extraction rate of Cr ( VI ) was 99.77%.
