摘　　要：甲醛(HCHO)是一种重要的大气反应活性指示剂和城市大气气溶胶的前体物,影响着对流层中的氧化容量。此外,作为一种有毒气体,过量的HCHO还会对人体健康造成极大的危害,因而实现HCHO的痕量检测有着十分重要的意义。综述了国内外HCHO痕量探测的研究进展,对HCHO的探测方法特别是光谱学探测方法,从探测原理、探测谱线以及光源的应用等多方面进行了详细的介绍。此外,对比了几种典型的HCHO标定装置,并从探测灵敏度、响应度、选择性、成本以及集成化等多个方面对不同痕量HCHO光谱学探测技术进行了分析与总结,最后对不同探测技术的外场测量应用进行了介绍。Formaldehyde(HCHO)is an important indicator of atmospheric reactivity and one of the main precursors of urban atmospheric aerosols,which controls the oxidation capacity in the troposphere.In addition,as a toxic gas,excessive HCHO will cause great harm to human health.Therefore,it is of great significance to realize the trace detection of HCHO.The research progress of trace detection of HCHO at home and abroad is reviewed,and the detection methods of HCHO,especially the spectroscopic detection methods,are introduced in detail from the detection principle,detection spectral line and the application of light source.In addition,several typical HCHO calibration devices are compared,and different trace HCHO detection technologies are analyzed and summarized from detection sensitivity,response,selectivity,cost,integration and so on.Finally,the applications of different detection technologies in field measurement are also introduced.
