| Abstract: | 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... |
