Abstract

The laws of the adsorption of aromatic compounds on the trialkylphosphine oxide–modified electrodes of a piezoelectric quartz resonator were studied. Differences in the time parameters of adsorption were applied to the development of procedures for the separate determination of phenol, toluene, and aniline in air mixtures. The combination of versatile and stable adsorbent films and selective adsorbent films but with short lifetimes improves the performance characteristics of a detector based on a modified piezoelectric quartz resonator. The air filtration of concomitant vapors improves the selectivity of determination.
