摘要
甲醛是室内空气的主要污染物之一,随着人们对室内空气污染的日益关注,对甲醛的准确及时检测显得更加重要。目前检测甲醛气体最为快速的方法就是传感器法。在综合分析了国内外甲醛气体传感器的研究现状的基础上,着重就测定甲醛的电化学传感器、基于化学发光的传感器、金属氧化物传感器、电子鼻、声表面波传感器的特性进行了阐述与剖析,指出了甲醛气体传感器存在的问题,并预测了其发展趋势。
Formaldehyde is one of main pollutions in indoor air. Along with people＇s increasing attentions on indoor air pollutions,accurate and rapid formaldehyde determination looks much more important. At present,the most rapid formaldehyde determination is the method with sensor. Therefore, features of those formaldehyde gas sensors such as electrochemical sensors, chemiluminescence sensors, metal oxide sensors, electronic noses and surface acoustic wave sensors were emphatically described and investigated based on comprehensive analyses of research statuses of formaldehyde gas sensors in home and abroad. Problems of those formaldehyde gas sensors were pointed out and their development trends were predicted.
