After the conditions were optimized, the linear relationship was good enough (r2=0.999 1) from 1.0 to 50.0 μg/L. The method detection limit was 0.224 μg/L and the method quantification limit was 0.896 μg/L. The RSDs of the spiked water were 4.15%~6.24%, and the recovery rates were 81.0%~115%. The total detection time of each sample is less than 40 minutes. The extraction and GC-MS-MS analysis of the proposed method are done online in one step. The method is easily operational, highly sensitive and strong antiinterference. The method is suitable for the determination of 2,4,6trichlorophenol in surface water, drinking water, industrial wastewater and so on. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
