Electrochemical and capacitive sensors based on Aquivion® D83-06A as sensing element are designed and tested. Electrodes are produced by modifying the sensing element with KOH and/or MWCNTs addition, and casting it on the surface of stainless steel plates. A sandwich sensor is obtained by coupling two steel plates with the thickened Aquivion® D83-06A layer. Devices are tested for ammonia sensing in the range 10-100 ppm in liquid, obtaining an electrochemical and capacitive response in presence of the analyte.

Abstract

Electrochemical and capacitive sensors based on Aquivion® D83-06A as sensing element are designed and tested. Electrodes are produced by modifying the sensing element with KOH and/or MWCNTs addition, and casting it on the surface of stainless steel plates. A sandwich sensor is obtained by coupling two steel plates with the thickened Aquivion® D83-06A layer. Devices are tested for ammonia sensing in the range 10-100 ppm in liquid, obtaining an electrochemical and capacitive response in presence of the analyte.
