Abstract : Herein, a novel polymer film modified pencil graphite electrode as an electrochemical sensor for the propranolol hydrochloride (PROP) is reported. A poly nicotinamide modified pencil graphite (Poly-NA-PGE) electrode was used for the electrochemical detection of propranolol hydrochloride using differential pulse voltammetry. The modified electrode was characterized by Scanning Electron Microscopy. Furthermore, the experimental parameters like pH of the supporting electrolyte, concentration of the nicotinamide and polymerisation cycles were optimized. The cyclic voltammetry of propranolol hydrochloride showcased an irreversible oxidation peak at 0.9361V. The sensor showed a linear range from 1μM - 20μM with a correlation co-efficient of 0.99825. The repeatability of the electrode was excellent with an RSD of 3.5%. The sensor was utilized effectually for the determination of propranolol from the commercially available pharmaceutical tablet.
