| Notes | Inorganic anions； n-Butyl acetate； Electromembrane extraction； Ion chromatography An electromembrane extractor was set up to extract inorganic anions fromn-butyl acetate using dei-onized water.Four inorganic anions in n-butyl acetate migrated through the pores of a polypropylene hollow fiber membrane,and were transported into deionized water inside the lumen of the hollow fiber by the appli-cation of 600Vd.c.Then the acceptor solution was analyzed by ion chromatography.The optimal extraction conditions were 600Vof applied voltage,600r/min of stirring speed and 5min of extraction time.The pro-cedure was applied to analyze inorganic anions in real n-butyl acetate sample with recoveries in the range of 95%-105%,which corresponded to linear range of 0.01-1mg/L and detection limits（LOD）of 0.001-0.050mg/L.The experimental results demonstrate that the proposed method is fast and effective. 22-1125/O6 HU Zhen-Zhen,WANG Lei ,YAO Chao-Ying,ZHU Yan,ZHANG Pei-Min1（Department of Chemistry,Xixi Campus,Zhejiang University,Hang |
