摘　　要：采用自动顶空固相微萃取（HS-SPME）技术与气相色谱联用同步分析水中1,4-二氯苯、1,2-二氯苯、1,3,5-三氯苯、1,2,4-三氯苯、1,2,3-三氯苯、六氯苯、硝基苯、对硝基甲苯、α-666、β-666、γ-666、δ-666、七氯、ρ,ρ′-DDE、ρ,ρ′-DDD、o,ρ′-DDT、ρ,ρ′-DDT17种有机物。方法的最低检出浓度为0.001~0.044μg/L,线性相关系数均大于0.999,相对标准偏差为1.4%~8.7%,加标回收率在81.3%~122.9%之间。A method for the determination of seventeen organic compounds in water has been developed,which was analyzed by automated HS-SPME and gas chromatography.Through automated sample pre-treatment,the precision and accuracy of the determination results were improved.And no organic solvent was used.The linearity in the detection range is good with the lowest determination limits of 0.001~0.044 μg/L.The relative standard deviations was 1.4%~8.7%.Test for recovery was made by standard addition method,and the results were 81.3%~122.9%.
