ABSTRACT
For the first time is suggested that the analyte itself, that is, motor oil can be used as a binder into a carbon-paste electrodes. It is revealed that the electroactive markers: o-nitrophenol, o-nitrobenzoic acid, 2,5-dinitrophenol can specifically interact, accumulate and reduce on the CPE surface modified by different motor oils. Three-component mixtures of markers can be used for distinguishing motor oils with PCA applied. And their univocal identification is also possible by further using the SIMCA.
