An electrochemical sensor for detection of vanillin in food samples using CuFe2O4 nanoparticles/ionic liquids modified carbon paste electrode
A highly selective electrochemical sensor modified with CuFe2O4 nanoparticles and the ionic liquid was constructed for the detection of vanillin. The sensor could recognize vanillin from its analogs and possible coexistent substances. The response peak current and vanillin concentration showed a good linear relationship in the range of 0.01 - 300.0 μM, with a sensitivity of 0.0923 μA μM-1. The detection limit was 0.008 μM (S/N = 3). Besides, the reproducibility and stability measurements were also evaluated. It was applied to the determination of vanillin in real samples with satisfactory results.
