摘要：
The development of a novel electrochemical sensor, based on modification of the carbon paste electrode with MgO/SWCNTs nanocomposite and 1-butyl-3-methylimidazolium hexafluoro phosphate (MgO/SWCNTs/BMPF6/CPE) has been reported. The electro-oxidative behavior of vanillin in food samples at MgO/SWCNTs/BMPF6/CPE using square wave and linear sweep voltammetry was investigated. The oxidation signal of vanillin at MgO/SWCNTs/BMPF6/CPE increased when compared with the unmodified electrode. The catalytic current showed a linear relationship with vanillin concentration in the range 0.02 to 800 mu M with a detection limit of 8.0 nM. The MgO/SWCNTs/BMPF6/CPE was applied for vanillin determination in food samples.
