摘要
挥发性有机物(TVOC)是室内空气中的主要污染物。采用Tenax-TA吸附管采集样品后,经热解析仪解析,气相色谱仪配氢火焰离子化检测器(FID)检测,用外标法定量测定空气中16种挥发性有机物。采用Tenax-TA吸附管-热解析的方法对《民用建筑工程室内环境污染控制规范》(GB50325-2020)16种组分挥发性有机物精密度、准确度进行验证,通过数据表明本方法重现性好、准确度高且检测成本较低,是民用建筑工程室内环境检测较理想的一种检测方法。
Volatile organic compound is a major pollutant in indoor air.The samples were collected by Tenax-TA adsorption tube,analyzed by thermal analyzer,analyzed by gas chromatograph with FID detector,and quantitatively determined 16 kinds of Volatile organic compound in air by external standard method.The precision and accuracy of 16 components of indoor environmental pollution control code for civil construction engineering(GB50325-2020) were verified by Tenax-TA adsorption tube-thermal analysis method,the data show that the method has good repeatability,high accuracy and low detection cost.It is an ideal method for indoor environment detection of civil building engineering.
