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