摘　　要：本文采用一种手工监测方法监测环境空气中的121种挥发性有机物(VOCs)。该方法比现有监测方法更全面、更准确、更简便,为环境空气中VOCs的监测提供更好的方法。该方法曲线线性良好,相关系数保持在0.9959~1.0000,检出限为0.2~2.0μg/m^(3),相对标准偏差不大于12.3%。研究表明,该方法适用于环境空气中VOCs的监测。In this paper,a manual monitoring method is used to monitor 121 volatile organic compounds(VOCs)in ambient air.This method is more comprehensive,accurate,and simpler than existing monitoring methods,and provides a better method for monitoring VOCs in ambient air.The curve of the method has good linearity,the correlation coefficient is kept in the range of 0.9960~1.0000,the detection limit is 0.2~2.0μg/m^(3),and the relative standard deviation is not more than 12.3%.Studies have shown that this method is suitable for monitoring VOCs in ambient air.
