摘要：

Negatively charged 1-butyl-4-methyl-pyridiniumtetrafluroborate (BMPTB) ionic liquid was electrochemically deposited on the surface of carbon paste electrode (CPE) by cyclic voltammetric (CV) technique in 0.1 M nitric acid. It exhibited an electrocatalytic activity towards the oxidation of DA, AA, and UA in 0.1 M phosphate buffer solution (pH 6.6). The effect of concentration, scan rate, and pH was studied for dopamine. The BMPTB/CPE showed an excellent electrocatalytic activity for selective detection of DA in the presence of AA and UA by using CV and differential pulse voltammetry (DPV) respectively. Detection limit of dopamine was found to be 1 x 10(-8) M. The present technique provides a novel method for the simultaneous determination of DA, M and UA in their mixture sample.
