监测挥发性有机物的SAW传感器的研究进展

Research progress of surface acoustic wave chemical sensor for monitoring volatile organic compounds

综述了可以连续操作和用于原位监测有机挥发性化合物的声表面波(SAW)化学传感器的研究进展。不锈钢包装和集成电路板的应用,使SAW传感器可以用于空气、土壤和水等在内的多种环境中监测有机挥发性化合物(VOCs)。介绍了根据常见地下水污染物氯代脂肪烃(如三氯乙烯)选择的高分子膜以及对传感器进行的优化。

The development of a surface-acoustic-wave （SAW） chemical sensor that can operate continuously and in situ detect volatile organic compounds is summarized. A ruggedized stainless-steel package and integrated circuit board allows the SAW sensor to be used a variety of media including air, soil and water to monitor valatile organic compounds（VOCs）. Polymers based on their response to groundwater contaminants—chlorinated aliphatic hydrocarbons （e. g. trichloroethylene） are introduced, and the optimization of the sensor is done.
