dc.description.abstractA glassy carbon electrode was modified with electropolymerized film of diphenylamine sulfonic acid (DPASA). Electropolymerization was performed by cyclic voltammetry in 0.1 M KCl solution. The modified electrode showed an excellent electrocatalytic effect towards oxidation of dopamine (DA) and ascorbic acid (AA). Electrostatic interaction between the negatively charged poly(DPASA) film and either cationic DA species or anionic AA species favorably contributed to the redox response of DA and AA. Anodic peaks of DA and AA in their mixture were well separated by ca 168 and -11.8 mV. The proposed modified electrode was utilized for selective determination of dopamine in the concentration range of 5.0 x 10(t7)-2.0 x 10(-5) M in the presence of high concentration of ascorbic acid. Detection limit was 6.5 x 10(-9) M.en_US
