A new voltammetric approach was developed for the determination of paracetamol in tablet and syrup samples using chemometric optimization. The method is based on the use of the gold nanoparticles–polyaniline (AuNPs−PA) modified pencil graphite electrode (PGE). Electrode system was fabricated by using the electrochemical reduction of gold on aniline modified pencil electrode to give gold nanoparticles. A 33 full factorial design was used to find optimal oxidation conditions of paracetamol on the AuNPs−PA−PGE. The optimal oxidation conditions of drug substance were found as –524 mV for the accumulation potential, 295 s for the accumulation time and pH 8.69 (for the phosphate buffer solution, 0.1 M). The determination of paracetamol was linear in the range of 2.0 × 10–7–6.0 × 10–6 M with a detection limit of 5 × 10–8 M. As a result, the proposed voltammetric approach gave satisfactory results for the determination of the related drug substance in tablets and syrup.
