| 摘 要： | 采用顶空固相微萃取（HS －SPME）技术萃取水中6种氯苯类化合物，全面分析对目标物萃取效率的影响因素，并确定萃取试验的最佳条件。用顶空固相微萃取联合气相色谱法（HS －SPME －GC）测定水中6种氯苯类化合物，方法在0.500 ng／L～2.00×10^5 ng／L范围内线性良好，检出限为0.05 ng／L ～2000 ng／L，空白样品加标回收率为69.8％～121％， RSD为4.8％～18.3％。用该方法测定实际水样，平行双样的相对偏差低于20％。

| Abstract: | The headspace solid phase microextraction （HS-SPME）method was applied to determine 6 chlo-robenzenes in water.The influence factors were analyzed that effect the extraction efficiency of the target com-pounds.As a result the optimum extraction conditions were determined.Within 0.500 ng/L~2.00 ＆#215;105 ng/L, linear is good;the detection limit is 0.05 ng/L ~2 000 ng/L;blank standard addition recovery was 69.8% ~121%,RSD was 4.8%~18.3%.Using the current method to determine the 6 chlorobenzenes in actual water samples,the relative deviation of parallel double samples is less than 20%. |
