摘要

This communication shows the improved performance of electrochemically-reduced graphene oxide (ERGO) modified electrodes for the square-wave voltammetric detection of cocaine (COC) and its main adulterants paracetamol (PAR), caffeine (CAF) and levamisole (LEV). The four compounds can be identified in a single voltammetric scan on the ERGO-modified electrode with adequate resolution of peaks and increase in current (at least 2-fold) in comparison with the unmodified electrode. Moreover, electrode fouling typically verified during the oxidation of CAF and LEV is eliminated. CAF and PAR were determined in a real COC sample and satisfactory recovery values were obtained (103 and 85%, respectively).
