摘　　要：目的:建立工作场所空气中二硫化碳的毛细管柱气相色谱测定方法。方法:以毛细管柱对被测样品中的二硫化碳进行分离,火焰光度检测器(FPD)进行检测。结果:二硫化碳浓度在0.02μg/ml^6.0μg/ml呈良好的线性关系,相关系数为0.9999;检出限为0.02μg/ml,最低检测浓度为0.03 mg/m3(以采集3.0L空气样品计);相对标准偏差小于5.0%,平均回收率为98%。结论:方法各项指标均符合GBZ/T210.4-2008《职业卫生标准制定指南第4部分:工作场所空气中化学物质测定方法》的要求,适用于工作场所空气中二硫化碳的测定。Objective ： To establish the method for detecting the concentrations of carbon disulfide in air of work-places by gas Chromatography with capillary, column. Methods： Carbon disulfide in sample liquid was separated with capillary column and detected by gas chromatography with FPD. Results： The linearity range was 0.02 μg/ml - 6.0 μg/ml, the correlation coefficient （r） was 0. 9999, and the detection limit was 0.02 μg/ml, the lowest detection concentration was 0.03 mg/m3 （ the air volume was 3 L）. The relative standard deviation was less then 5.0%, the average recovery rate was 98%. Conclusion： The method could meet the requirements of “Guide for establishment of occupational heath standards - Part 4 ： Determination methods for air chemicals in workplace” and it is feasible for determination of carbon disulfide in workplace air.
