摘要
采用小型环境舱模拟聚氯乙烯(PVC)卷材地板在实际使用过程中挥发性有机化合物(VOC)的释放过程,利用热解析-气相色谱质谱联用(TD-GC-MS)法测定总挥发性有机化合物(TVOC)释放量.各组分检出限为0.2—0.4μg·m^-3(S/N=3),定量限为0.6—1.4μg·m^-3(S/N=10).对20个PVC卷材地板的TVOC释放规律和主要污染物来源进行了分析.
Small environment chambers were used to simulate the volatile organic compounds(VOC)release process of polyvinyl chloride(PVC)floors and the release of TVOC was determined by thermal desorption gas chromatography mass spectrometry(TD-GC-MS).The limits of detection and the limits of quantitation of 9 VOCs were 0.2—0.4μg·m^-3(S/N=3)and 0.6—1.4μg·m^-3(S/N=10).The release law of TVOC and main pollutant sources of 20 PVC floors were analyzed.
