The invention discloses a method for catching and detecting static headspace gas chromatography electrons of eleven chlorobenzene compounds in water, which belongs to the field of a water pollution detection technology. Eleven chlorobenzene compounds are as follows: 1, 4-dichlorobenzene, 1, 3-dichlorobenzene, 1, 2-dichlorobenzene, 1, 3, 5-trichlorobenzene, 1, 2, 4-trichlorobenzene, 1, 2, 3-trichlorobenzene, 1, 2, 3, 4, 5-tetrachlorobenzene, 1, 2, 4, 5-tetrachlorobenzene, pentachlorobenzene and hexachlorobenzene. According to the method, a water sample containing 20% of sodium chloride is added into a 20mL of headspace bottle, an aluminium cover containing PTFE (polytetrafluoroethylene) is utilized to seal instantly, and 800 [mu] L of gas in a top space of the headspace bottle is taken to detect in a gaschromatograph after the headspace bottle added with the water sample is balanced with the vibrating speed of 500rpm for 30 min at 70 DEG C. A detection limit of the eleven chlorobenzene compounds is 0.0002-0.04 [mu] g / L, and the recovery rate is 83-116%. The method provided by the invention is environmentally friendly, free of organic solvent, simple to operate, wide in linear range, good in repeatability, high in recovery rate and is capable of quickly detecting the concentration of the chlorobenzene compounds in water.
