摘　　要：塑胶跑道中的有机挥发物二硫化碳对人体危害较大。通过对比分析不同活性炭管对塑胶跑道中有机挥发物二硫化碳的结果影响,提出了适用于分析塑胶跑道中二硫化碳的分析方法。在规定的测试条件下,规则中微孔分布的Scalpha 600捕集管对二硫化碳的吸附效率最高,且二硫化碳在0.01~2.0μg的浓度范围内线性良好,线性相关系数为0.9997,检出限和定量限分别为0.0010 mg/m 3和0.0035 mg/m 3,相对标准偏差小于10%,加标回收率为100.3%~105.9%。The organic volatile carbon disulfide in plastic runways harms humans.In this paper,a suitable method for the analysis of VOC carbon disulfide in plastic runways was proposed by comparing and analyzing the effects of different activated carbon tubes on the results of organic volatile carbon disulfide in plastic runways.Under the given conditions,the Scalpha 600 activated carbon tube with regular micropore distribution has the highest adsorption efficiency for carbon disulfide,in which the linear correlation coefficient of carbon disulfide is 0.9997 in the concentration range of 0.01~2.0μg.The detection limit and quantitative limit are 0.0010 mg/m 3 and 0.0035 mg/m 3,respectively.In addition,the relative standard deviation is less than 10%,and the recoveries are within 100.3%~105.9%.This method is simple,rapid,has high adsorption efficiency and good reproducibility for evaluating disulfide carbon released by the plastic runway.
