Determination of DMMP Using a Polymer Coated QCM Sensor

Article Preview

Abstract:

A quartz crystal microbalance (QCM) modified with a thin layer of fluorinated polymer was utilized to determine dimethylmethyl phosphonate (DMMP). Determination was based on the frequency shifts due to the adsorption and desorption of the compound at the surface of modified quartz crystal electrode. Fluorosiloxane was utilized onto the surface of the sensor. The frequency shifts were linear against the concentration of DMMP within the concentration range of 30~210mg•m-3. Good selectivity and sensitivity were obtained with the sensor for DMMP. The detection limit was 10.1 mg•m-3.
