Determination of 15 kinds of volatile organic compounds including halogenated hydrocarbons,benzene, chlorobenzene etc. in drinking water by headspace capillary GC-MS method was established. The 15 kinds of volatile organic compounds in drinking water were determined by directly into the sample headspace capillary GC-MS. The column was DB-624 quartz capillary column (60 m ×0.25 mm, 1.8μm),and the temperature was programmed. The method had good linear with linear correlation coefficient more than 0.996,and the detection limit was 0.10-0.22μg/L. The average recovery rate was 94%-103%,and the relative standard deviation of determination results was 2.9%-6.7%(n=7). The method is simple,rapid,and the results is in consistent with GB 5749-2006.
