摘　　要：介绍了甲醛检测方法的新进展和常用的仪器 ,指出发展灵敏度高、选择性好、能够实现现场分析或长期稳定地实时在线监测的新方法和新仪器仍然是空气中甲醛监测研究的一个重要方向。Detection and monitoring of formaldehyde in ambient air is of great importance since formaldehyde is of dangerous toxicity and has been ditributed widely in environment. The sampling technique involved in procedures and other analytical methodologies including spectrophotometric analysis, electrochemical analysis, chromatography and sensing techniques were briefly reviewed and the commercial instruments for formaldehyde detection were evaluated in this paper. it has been concluded that developing new method and new apparatus with high sensitivity and high selectivity for in situ analysis and real time on-line monitoring will guide the direction in future.
