| Abstract: | The method of liquid - liquid extraction and rapid detection of 24 kinds of SVOCs in source water by GC - MS was studied. 250 mL water sample was extracted by benzene, and the constant volume was 2 mL. The recovery of the alkaline component and neutral fraction was 66.8% - 156% , and the recovery of the acidic component was 32.5% -45.6%. The RSD of detection result was 1.23% - 6.55% （ n = 7）. Based on The Monitoring Analysis Method of Water and Waste Water（ the 4th edition） , the selection of solvent and extraction time were further optimized, and the volume of samplings and organic solvents were reduced. |
