Abstract: The electrochemical properties of furan were investigated. On this basis, we developed a rapid electrochemical method for the determination of furan in food. The cyclic voltammetry showed that a well-defined oxidation peak was observed at 1.80 V but no reduction peak appeared, indicating that the electrochemical reaction of furan is irreversible. The experimental conditions were optimized with differential pulse voltammetry as follows: acetonitrile as solvent, potential increment 0.005 V, pulse interval 0.3 s, and electrolyte concentration 0.15 mol/L. The oxidation peak current (Ip) had a good linear relationship with furan concentration (Cfuran) in the range of 2 × 10-6–6 × 10-5 mol/L, which was fitted as follows: Ip = 0.046 6Cfuran + 0.565 (R2 = 0.996 8), and the limit of detection (LODs) of the proposed method was 0.55 μmol/L (RSN = 3). The presence of furan in different foods was quantified by this method, and the average recoveries for spiked samples were in the range of 94.60%–98.41%. The detection results well agreed with those obtained with gas chromatography-mass spectrometry (GC-MS). With the characteristics of simple sample preparation, simple operation and rapid detection, this method is useful for rapid determination of furan in food samples .
