气体传感器在室内甲醛监测中的研究进展

Research Progress of Gas Sensor in Indoor Formaldehyde Monitoring

气体传感器广泛用于环境监测中,在室内气体监控方面也有良好的应用前景。甲醛是一种重要的工业原料,其广泛应用在化工、食品、建材等方面,但是甲醛毒性大,具有致癌作用。阐述监测甲醛气体的传统方法和新型传感器法,探讨它们的原理,总结其优缺点,详细介绍新型气体传感器在监控甲醛方面的研究进展,并进一步提出了存在的问题和未来的发展方向。

Gas sensors are widely used in environmental monitoring and have good application prospects in indoor gas monitoring.Formaldehyde is an important industrial raw material,which is widely used in chemical industry,food,building materials and so on.However,formaldehyde is toxic and carcinogenic.In this paper,the traditional method and new sensor method of monitoring formaldehyde gas were expounded,their principles were discussed,and their advantages and disadvantages were summarized.The research progress of new gas sensor in monitoring formaldehyde was described in detail,and the existing problems and future development direction were further put forward.
