摘要
针对室内空气家中的甲醛特点,对传统的乙酰丙酮分光光度法在采样时间、样品收集、采样流量等方面进行优化,优化后的空气质量测定方法提高了室内空气监测准确性、拥有简便性快捷性的特点。对某市12户住宅室内的甲醛含量进行了检测,其中8户住宅超过了国家室内空气质量标准GB/T18883-2002规定的甲醛质量浓度0.1 mg/m3。
According to the characteristics of formaldehyde in indoor air, traditional acetylacetone spectrophotometric method was optimized in the aspects of sampling, sample collection, sample flow and so on; the optimized air quality determination method improved indoor air monitoring accuracy, had simple and fast characteristics. In this paper, indoor air formaldehyde content of 12 residences in a city were detected, indoor air formaldehyde content of 8 residences was over the national indoor air quality standard GB/T 18883-2002.
