摘要

Continuous liquid-liquid extraction (CLLE) and closed loop stripping analysis (CLSA) were chosen for development and evaluation as the most appropriate extraction and concentration procedures for broad spectrum analysis of synthetic organic chemicals (SOCs) in natural waters. A set of 16 SOC standards was selected which would be representative of the wide range of SOCs which are encountered as pollutants in natural waters. Method optimization experiments were carried out by determining the percent recoveries of these representative SOCs under a variety of analytical conditions. Using the optimized analytical conditions, the CLLE and CLSA procedures were applied to natural waters so that water matrix effects could be studied and broad spectrum SOC analysis, identification, and quantification performed. A final evaluation of the developed methods was carried out by comparing results from four water samples, which were analyzed by the CLLE and CLSA methods, to results obtained at a qualified laboratory using the currently recommended EPA methods.
