Abstract
The paper presents the results of investigation on a prototype sensor for measurement of benzaldehyde and formaldehyde in air. Sensitivity, limit of quantification and coefficient of selectivity of the sensor have been determined as a function of membrane thickness and electrode type using square wave voltammetry (SWV) technique. The working and counter electrodes were made of platinum and gold. Ionic liquids 1-hexyl, 3-methylimidazolium bis (trifluoromethanesulfonyl)imide constituted an internal electrolyte. Polydimethylsiloxane (PDMS) membrane separated gaseous medium from the electrolyte.
