In this work, Poly eosin modified carbon paste electrode was prepared by electropolymerisation method by using cyclic voltammetry technique. This poly (Eosin) modified CPE exhibited an excellent electrocatalytic activity towards the oxidation PA and FA in presence of EP in 0.2M PBS at pH 7.0. The effect of pH and sweep rate was studied. The limit of detection of PA and FA were found to be 0.06 and 0.04 μM, respectively. An electrochemical simultaneous separation was observed in a binary mixture containing PA, FA and EP and interference study was done by differential pulse voltammetry technique. Finally, the prepared fabricated sensor exhibits good sensitivity, and selectivity.
