摘　　要：7种氯苯类化合物氯苯、2-氯甲苯、3-氯甲苯、4-氯甲苯、1,2,3-三氯苯、1,2,4-三氯苯和1,3,5-三氯苯在5.00~200μg/L浓度范围内线性良好,加标回收率为87.5%~104.5%,相对标准偏差为1.9%~4.7%(n=6)。本方法操作简便快速,检出限低,精密度和准确度好,可用于水中氯苯类化合物的痕量分析。A headspace-gas chromatography mass spectrometry method for the determination of chlorobenzene,2-chlorotoluene,3-chlorotoluene,4-chlorotoluene,1,2,3-trichlorobenzene,1,2,4-trichlorobenzene and 1,3,5-trichlorobenzene in water was established.The seven chlorobenzene compounds had good linearity in the concentration range of 5.00-200μg/L,the recoveries were 87.5%-104.5%,and the relative standard deviations were 1.9%-4.7%(n=6).The method has the advantages of simple and rapid operation,low detection limit,good precision and accuracy,and can be used for trace analysis of chlorobenzenes in water.
