Abstract

During the last decade many and considerable advances are being realized in the field of detection and measurement using surface acoustic wave (SAW) and quartz crystal microbalances (QCM) based sensors. Thus, the current work attempts to investigate the contribution of polymers based polysiloxane mixed with zeolite in sensitive layers used in the above cited sensors types for detection of organic and organophosphorus toxics. The inverse gas chromatography technique (IGC) which is proven as versatile method for the polymer's surface exploration was used to understand phenomenon governing the adsorption occurred on the mixed polymer zeolite. The polyphenylmethylsiloxane/HZSM-5 was used as stationary phase to determine the specific retention volumes and the interaction parameters, on two ranges of temperature (200-230°C and 270-300°C). The obtained results with the organophosphorus solutes reveal the existent of strong affinity of retention, which let us to suggest that the prepared blend can be used as sensitive layers for the detection of toxics.
