SENSORY FEATURES OF TIACALIXARENE FILMS TOWARDS TOXIC AND EXPLOSIVE VOLETILE COMPOUNDS

Abstract

The work is dedicated to the investigation of adsorption features of functionalized derivatives of tiacalix[4]arenes towards phosphorus and chlorine organic volatile compound as well as well as to nitroaromatic simulators of explosive organic compounds. Experiments were carried out with quartz resonators array covered with the films of calixarene receptors. Experiments were performed at the concentration levels 10–1000 ppm, that corresponds to 100–10 dilution of the saturated vapours of analytes. Detection limits reached 10–100 ppm depending on the type of analyzed toxic substances; operational speed was about 10–20 sec.
