Differenzpuls-voltammetrische Bestimmung von Dopamin mit elektrochemisch vorbehandelten Elektroden

The electroanalytical method proposed permits a sensitive and selective determination of dopamine in the presence of ascorbic acid applying a fast galvanostatic pretreatment of the carbon electrodes. The effect of the electrochemical pretreatment at glassy carbon electrode was compared with that of carbon fibre array electrode
