摘要
目的建立酮洛芬生产车间空气中3-氯甲基苯乙酮的测定方法。方法空气中3-氯甲基苯乙酮用活性炭管采样,乙酸乙酯解吸,经FFAP柱分离,FID检测器检测,以保留时间定性,峰面积定量。结果3-氯甲基苯乙酮在5～1000μg/ml范围呈线性关系,相关系数为0.9992,检出限为1.67mg/m3,平均解吸效率为92.2%～101.5%,100mg活性炭对3-氯甲基苯乙酮的穿透容量是5.0mg。结论该法适用于工作场所空气中的3-氯甲基苯乙酮现场监测。
Objective To establish a method for determination of 3’-chloromethylacetophenone in the air of ketoprofen workplaces. Methods The 3’-chloromethylacetophenone was sampled using activated carbon tube and then desorbed by ethyl acetate. All the components were determined by gas chromatograph with FID after complete separation with FFAP capillary column. Results This method presented a linear relation within 5-1 000 μg/ml, r value was 0.999 2. The detection limit was 1.67 mg/m3. Desorption efficiencies were 92....
