A continuous flow liquid membrane extraction (CFLME)–C 18 precolumn-liquid chromatography system was developed for preconcentration and determination of chlorinated phenols (CPs). After preconcentration by CFLME, which is based on the combination of continuous flow liquid–liquid extraction and supported liquid membrane, CPs were enriched in 960 l of 0.5 mol… (More)
