A new and simple strategy for the simultaneous determination of ethanol and methanol in fuel ethanol using cyclic voltammetry at a gold electrode is reported. A fuel ethanol aliquot was added into an elec- trochemical cell containing 0.5 mol L-1 NaoH and 0.1% (vv) of methanol as the electrolyte and both ana- lytes were determined using cyclic voltammetry. Ethanol was selectively detected at +0.19 v and both compounds were detected at +1.20 V. Current subtraction (using a correction factor) could be used for the selective determination of methanol. The limits of detection estimated be 0.0288 and were to 0.045% (viv) for ethanol and methanol. respectively. The proposed method presented similar results to those obtained by gas chromatography at a 95% confidence level
