Determination of Eugenol at a Nano-WO_3 Modified Carbon Paste Electrode
Abstract:The voltammetric behaviour of eugenol was investigated by cyclic voltammetry(CV),linear-sweep voltammetry(LSV) and differential pulse voltammtry(DPV) on a nano-WO3 modified carbon paste electrode(CPE).It is found that nano-WO3 significantly enhances the oxidation peak current of eugenol.All the experimental parameters were optimized and a sensitive electrochemical method was developed for the determination of eugenol.The oxidation peak current is proportional to the concentration of eugenol from 8.0×10-8mol/L to 2.0×10-4mol/L,The detection limit is about 1.0×10-8mol/L for 90s accumulation.The methods was appropriate for the detection of sample,and the recovery rate is between 96.5% to 109%.
