| 中文摘要: |
| 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～2.00×105 ng/L范围内线性良好，检出限为0.05 ng/L～2 000 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%。 |

| The headspace solid phase microextraction (HS SPME) method was applied to determine 6 chlorobenzenes in water.The influence factors were analyzed that effect the extraction efficiency of the target compounds. As a result the optimum extraction conditions were determined. Within 0.500 ng/L～2.00×105 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%. |
