Title: Electrochemical behavior of dopamine at a mercury electrode in the presence of citrate: Analytical applications

Abstract: Dopamine can be determined by voltammetric methods using a mercury electrode, previously oxidized at +0.30 V. The oxidation product formed is stabilized in the presence of citrate and undergoes reduction at -0.31 V. This work describes the electrochemical behavior of dopamine at a mercury electrode in the presence of citrate and its application in the development of a square-wave voltammetric method for the dopamine determination in pharmaceutical formulations. The method was in-house validated for determination of dopamine in injectable formulations. The detectability of the method was 0.02 mu g ml(-1).
