摘要: Based on the electrocatalytic oxidation of levodopa at gold electrode and the reduction of permanganate at platinum electrode, a novel flow injection irreversible biamperometric method is developed for the determination of levodopa under the potential difference of 0 V imposed between two electrodes. In H2SO4 solution, the linear relationships between currents and the concentrations of levodopa are obtained in the range from 0.04mg/L to 20mg/L with the detection limit of 0.012mg/L. The proposed method is applied to the determination of levodopa in pharmaceutical preparations.
