室内化学品中挥发性有机化合物的挥发特征

Characterization of Volatile Organic Compounds from Indoor Materials

用气相色谱顶空分析方法和气相色谱—质谱联机分析鉴定了８种室内化学品中挥发性有机化合物成分，包括油漆、地板蜡、地板清洁保护剂、彩色涂料、空气清新剂、壁纸胶等。每种材料经ＧＣ—ＭＳ鉴定出３～３０种化合物，各种材料挥发性有机物的种类、数量及挥发速率各不相同。挥发出的有机物包括烷烃、烯烃、醇、醛、醚、酯以及苯系物。测试小室动态试验结果表明，油漆中挥发性有机物流出浓度与时间的关系符合二项指数方程。

Volatile organic compounds emitted from eight indoor materials including paint,wallpaper glue,maticolor coat,floorwax floorcovering and airfreshener and were analyzed by headspace GC FID and GC MS.About 3-30 organic compounds were detected from each material.It was shown that the emitted compounds and emission rate from different materials were different.The emitted compounds included paraffin,olefine,alcohol,aldehyde,ether,ester and aromatic compounds.The results of dynamic experiments in test chamber showed that the chamber concentration of volatile organic compounds from paint VS. time data follows a double exponentequation.
