Method for determining content of hexachlorocyclopentadiene in water by headspace-gas chromatography/mass spectrometry

The invention discloses a method for determining the content of hexachlorocyclopentadiene in water through headspace-gas chromatography/mass spectrometry, and belongs to the technical field of analysis and detection method.According to the method, the headspace-gas chromatography/mass spectrometry technology is adopted, an analysis method for determining hexachlorocyclopentadiene in water is established, the number of intermediate links is small, operation is easy, and the method is suitable for industrial production. According to the present invention, the photolysis loss of hexachlorocyclopentadiene is reduced, the accuracy of the determination result is high, the precision is good, the detection limit of the method is 0.3 [mu] g/L, the RSD is less than or equal to 5.8%, the blank adding standard recovery rate is 96.3-108%, and the method can be used for determination of surface water, underground water and sewage treatment export samples. 本发明公开了一种顶空-气相色谱/质谱法测定水中六氯环戊二烯含量的方法，属于分析检测方法技术领域，本发明采用顶空-气相色谱/质谱技术，建立
