论文摘要
对土壤中有机污染物的长期监测是一个主要的环境挑战。我们建议通过开发专门与H2S反应的聚合物的开发来解决这个问题，涂层表面声波传感器设计为具有化合物的被动合作目标，并使用地面穿透雷达探测其响应，从而提供了在地下环境中监测H2S的能力。选择性是通过在网状聚合物基质中包括铅（ii）阳离子来带来的，该聚合物基质可以作为薄层沉积在表面声波传感器上。我们展示了一种信号增强机制，其中吸水会放大信号检测，从而使传感器在充满水分饱和的地下环境中对H2S最敏感。
Long-term monitoring of organic pollutants in the soil is a major environmental challenge. We propose to meet this issue by the development of a polymer dedicated to selectively react with H2S, coating surface acoustic wave transducers designed as passive cooperative targets with the compound, and probing their response using Ground Penetrating RADAR, thus providing the capability to monitor the presence of H2S in the subsurface environment. The selectivity is brought by including lead(II) cation in a reticulated polymer matrix which can be deposited as a thin layer on a surface acoustic wave sensor. We demonstrate a signal enhancement mechanism in which water absorption magnifies the signal detection, making the sensor most sensitive to H2S in an underground environment saturated with moisture.
