A simple and rapid voltammetric method based on a disposable electrochemically pretreated screen-printed carbon electrode is proposed for the determination of L-dopa. Under optimum differential pulse voltammetry conditions a limit of detection of 3.6x10(-7)M for L-dopa was obtained. The method was successfully applied to the determination of L-dopa in a commercial pharmaceutical formulation.
