The electrochemical behavior of maltol at a multi-walled carbon nanotube(MWNTs) modified glassy carbon electrodes was investigated by cyclic voltammetry(CV) and differential pulse voltammetry(DPV).A direct electroanalytical method for the determination of maltol in beverages was developed.In the medium NH₃·H₂O-NH₄Cl(pH=8.5),maltol produces an irreversible oxidation peak at 0.55 V(vs.SCE) on the MWNTs modified electrode.The modified electrode exhibits good performance for the electrochemical reaction of maltol.The anodic peak current of maltol is linearly dependent on its concentration in a range from 5.0×10^-6 to 9.0×10^-4 mol/L,with a detection limit of 2.0×10^-6 mol/L.The relative standard deviation is 1.1% for a solution containing 5.0×10^-5 mol/L maltol(n=10).This modified electrode has a good stability.It can be applied to the direct determination of maltol in beverages without complicated and time-consuming pretreatment.The modified electrode has been satisfactorily used for the determination of maltol in beer,cola and grape wine.The recoveries are in a range of 98%~103%.
