| Abstract: | This paper developed an analysis method for determining 25 volatile organic compounds in surface water by headspace-trap gas chromatography/mass spectrometry.The experimental condition of headspace-trap were optimized by orthogonal experiment design,the correlation coefficient were higher than 0.995,the recovery of standard addition was 90％ ～ 110％,the method detection limit were 0.08 ～0.39μg/L,the instrument detection limit were lower than 0.04 μg/L,the relative standard deviation （RSD） were 0.7％ ～4.8％.This method has high accuracy and sensitivity,can meet requirement for the determination of 25 VOCs in surface water. |
