教室空气污染分析及其解决方案研究

Analysis and Solution Scheme of Classroom Air Pollution

分别采用气相色谱法和分光光度法对某大学五间教室内空气中苯、甲醛含量进行了测定。根据测定结果,参照国家有关室内环境质量指标,对上述教室内的空气质量进行了评价。分析教室中空气污染的来源,提出相应的解决方案,对于提高教室空气质量具有一定的指导作用。

The concentrations of benzene and formaldehyde in five classrooms of a certain university were determined respectively by means of capillary gas chromatography and ultraviolet-visible spectrophotometry. According to the National Indoor Air Quality Standard （ GB/T 18883-2002） , the indoor air quality of the five classrooms was evaluated. By analyzing the source of pollutants, corresponding solution schemes are proposed. It is helpful for air quality improvement in classroom.
