A carbon paste electrode modified with DL-alanine was investigated. The poly (alanine) modified carbon paste electrode (MCPE) showed excellent electrocatalytic effect on the oxidation of dopamine (DA) and ascorbic acid (AA). Favourable electrostatic interaction between negatively charged poly (alanine) film and cationic species of DA or anionic species of AA may mainly contribute to the response of DA and AA at this electrode. The anodic peaks of AA and DA were separated at about 204 mV at the poly (alanine) MCPE. Thus DA and AAcan be determined.
