ABSTRACT

The micro gold electrode modified by thiol layer was used as a working electrode in the cyclic voltammetry method. This analytical system was used for determining the neutral smell compounds: geraniol and coumarin. The decrease in reduction current value of [Fe(CN)6] ^-3 ions was observed already at the concentration of 10^-5 M of the compound investigated. The dimensions of these changes were different for each compound and their discrimination by the above sensor was possible.
