摘　　要：为确保检验结果准确,统一操作方法,验证现有试验条件(包括仪器、设备人员及环境等),采用活性炭吸附/二硫化碳解吸,气相色谱法FID检测器分析,根据保留时间峰面积定性,外标法定量,分析固定污染源中10种氯苯类化合物。实验表明,10种氯苯类化合物在1.0~50.0μg/m L浓度范围内线性关系良好,实验室检测出的检出限小于或等于方法所规定的检出限,实验室方法检出限及测定下限满足标准方法要求,测定高、中、低3种浓度水平的样品检测结果的准确性和重复性,适应于目前实验室的氯苯类的检测要求。In order to ensure the accuracy of the inspection results,unify the operating methods,and verify the existing test conditions(including instruments,equipment personnel,and environment),activated carbon adsorption/carbon disulfide desorption was used,and gas chromatography was used for FID detector analysis.Qualitative analysis was conducted based on the retention time peak area,and external standard method was used for quantitative analysis of 10 chlorobenzene compounds in fixed pollution sources.Indicating that 10 chlorobenzenes are present in the range of 1.0 to 50.0μg/mL.The linear relationship within the concentration range of g/mL is good,and the detection limit detected in the laboratory is less than or equal to the detection limit specified by the method.The detection limit and lower limit of the laboratory method meet the requirements of the standard method.The accuracy and repeatability of the test results for samples with high,medium,and low concentration levels were suitable for the current detection requirements of chlorobenzenes in the laboratory.
