Electrochemical Response of Dopamine in Presence of Uric Acid at Pregabalin Modified Carbon Paste Electrode: A Cyclic Voltammetric Study

Tanuja SB, Kumara Swamy BE and Vasantakumar Pai K

The electrochemical analysis of dopamine and uric acid was performed at Pregabalin modified carbon paste electrode by cyclic voltammetry in 0.2M phosphate buffer solution of pH 7.5 at scan rate 100 mV/s. The Pregabalin modified carbon paste electrode showed an increase in anodic peak current as compared to the bare carbon paste electrode. The pregabalin modified carbon paste electrode showed excellent electrocatalytic activity for selective determination of dopamine and uric acid by differential pulse voltammetry technique. Several elctrochemical parameters like effect of pH, Scan rate, different concentrations of dopamine and uric acid were studied at Pregabalin modified carbon paste electrode. The modified Pregabalin carbon paste electrode behaves like selective electrochemical sensor for detection of dopamine and uric acid.
