| Abstract: | This study established a method to determine 25 kinds of volatile organic compounds in water by purge and trap in combination with gas chromatography and mass spectrometry （C,C/MS）. The recovery ratios of the method were 90% - 119%. RF RSD was less than 20%. Using this method, the range of the lowest detection limits for 25 kinds of VOCs was 0. 04 μg/L 0. 22 μg/L. The method is simple, quick, sensitive and accurate, bringing no contamination. It is applicable for the determina- tion of VOCs in environmental water, underground water and drinking water samples. |
