摘要
就办公室内家俱释放的挥发性有机物(VOC)的组成和含量进行跟踪测定,在查阅国内资料的基础上,选择了苯、甲苯、对(间)二甲苯、邻二甲苯、苯乙烯、乙苯、乙酸丁酯、十一烷作为应识别组分,进行分析研究。结果表明,家俱释放的VOCs成份复杂,有大量的未识别组份,需要进一步定性研究;在已识别的8种组份中甲苯含量最高,二甲苯次之,而苯和苯乙稀含量最少;家俱中VOCs的释放随时间增长,浓度逐步降低,5天内降幅可达40%以上,且可满足GB/T18883-2002《室内空气质量标准》中关于TVOC的限量值要求。
The tracking-measurement of the composition and content of volatile organic compound （VOC） is focused. The benzene, toluene, p/m-xylene, styrene, ethylbenzene, butyl acetate and undecane are chosen to be the recognizable group to analyze. The result shows that the composition of the VOCs released by office-use furniture is very complex, containing a great number of unrecognizable compounds and calls for further study. Among the recognized eight compounds the toluene is the most followed by xylene while benzene and styrene are the least. The concentration of the VOCs gradually decreases as the time goes on. The amplitude can be above 40 % within 5 days and can meet the TVOC-limit requirement cited in the GB/T18883-2002 ‘Indoor Air Quality Standard＇.
