摘　　要：目的:建立工作场所空气中氨基苯甲醚的测定方法。方法:硅胶管采样,甲醇解吸,气相色谱仪测定。采用OV-17填充柱和FFAP毛细管柱,氢焰离子化检测器,以保留时间定性,峰面积定量。结果:空气中氨基苯甲醚在0.5 mg/ml^40.0 mg/ml范围内具有良好的线性关系,相关系数r>0.9996,最低检出浓度为3.3 mg/m3(以采集7.5 L空气样品计),回收率85%~98%;相对标准偏差2.9%~4.7%。样品在室温下可稳定7 d。结论:方法灵敏度较高,操作简便,均满足工作场所空气监测的需要。Objective：To establish an GC-FID method fpr determination of aminoanisole in the workplace air.Methods： Aminoanisole was sampled by solid sorbent tube with silica gel,and determined by GC-FID after desorbed by methanol.OV-17 filled column and FFAP capillary column were used for analysis,the retain time was used for qualitation and the peak area was used for quantitation.Results： The linear was good at the range of 0.5 mg/ml-40 mg/ml with the correlation coefficient of 0.9996;the limit of determination for aminoanisole residue was 3.3 mg/m3（calculated with 7.5 L air sample）,the recovery were 855-98%,with the relative standard deviation（RSD） of 2.9%-4.7%.The sample were stable at room temperature for 7 days.Conclusion： This method produced good sensitivity and simple to operate,it′s suitable for analysis aminoanisole in the workplace air.
