| Popis: | An electroanalytical approach based on electro-generated addition product is reported. Determination of dopamine in the presence of sodium 4-aminobenzenesulfonate as a nucleophile is given as an example. The reduction current for the addition product in the oxidized state to that in the reduced state was investigated by voltammetry and amperometry with flow-injection analysis. The present work shows concentration measurement of dopamine in the 10−8 M scale using bare glassy carbon electrodes. Keywords: Dopamine, Addition product, Voltammetry, Amperometry, Flow-injection analysis |
