Abstract
Abstract Poly (allura red) modified carbon paste electrode (MCPE) sensor is developed for the electrochemical determination of Adrenaline (AD) in the presence of Uric acid (UA), by cyclic voltammetric and differential pulse voltammetric techniques. Developed Poly (allura red) MCPE is more sensitive and selective. The effect of pH, scan rate and concentration on the oxidation of adrenaline were studied, LOD 6.8 µM, LOQ 22 µM for AD and LOD 17 µM, LOQ 54 µM for UA respectively and the poly (allura red) modified carbon paste electrode is applied for the simultaneous determination of adrenaline and Uric acid, the Poly (allura red) MCPE has capable of determining both AD and UA individually with two identical different oxidation peaks for AD and UA. This method can be used for some other bioactive molecules.
