چکیده
Aged distilled beverages (cognac and brandy) contain phenolic antioxidants as their quality markers. Voltammetric sensors based on the carbon nanotubes electropolymerized pyrocatechol violet (PCV) or p-aminobenzoic acid (ABA) were developed for simultaneous determination of in cognac brandy. The polymerization conditions PCV ABA optimized. Sensors allow sensitive gallic ellagic acids well syringaldehyde vanillin. analytical characteristics are improved vs. other modified electrodes. show selectivity presence typical interferences natural phenolics. that tested brandy samples.
