Abstract

A multiwall carbon nanotubes-modified carbon paste electrode (MWCNTs/MCPE) wasfabricated and used to study the electrooxidation of penicillamine (PA) by electrochemicalmethods in the presence of methyldopa (MDOP) as a homogeneous mediator. Theelectrochemical oxidation of PA on the new sensor has been carefully studied. The kineticparameters such as electron transfer coefficient, α , and catalytic reaction rate constant, K/h, werealso determined using electrochemical approaches. The electrocatalytic oxidation peak currentof PA showed a linear dependent on the PA concentrations and linear calibration curves wereobtained in the ranges of 0. 2-250. 0 μ M of PA concentration with square wave voltammetry(SWV) method. The detection limit (3σ ) was determined as 0. 1 μ M. This sensor was alsoexamined as a fast, selective, simple and precise new sensor for voltammetric determination ofPA in real samples such as drug and urine.
