摘要
目的:建立工作场所中丙酮、乙酸乙酯、丁酮、苯、甲苯、乙苯、对二甲苯、间二甲苯、邻二甲苯、苯乙烯和环己酮同时测定方法。方法:采用活性炭管吸附空气样品,经二硫化碳解吸后进样,AC20毛细管柱分离,FID检测器检测。结果:被测化合物在AC20毛细管柱上分离良好,工作曲线的相关系数r均在0.999以上,相对标准偏差及加标回收率均满意。结论:该方法适合空气中丙酮、乙酸乙酯、丁酮、苯、甲苯、乙苯、对二甲苯、间二甲苯、邻二甲苯、苯乙烯和环己酮的同时测定。
Objective：To establish a method for simultaneous determination of acetone,ethyl acetate,butyl benzene,toluene,xylene,ethylbenzene,xylene,styrene and cyclohexanone in workplace air by capillary gas chromatography.Methods： Air samples were collected using active carbon tubes and desorbed with carbon bisulfide.The sample solutions were separated with an,AC20 capillary column,and detected using FID detector.Results： All the target chemicals were separated well on AC20 cilumn and had correlation coefficients larger than 0.999.The relative standard deviations and recoveries were satisfactory.Conclusion： This method is suitable for the determination of these chemicals in workplace air simultaneously.
