Abstract
A carbon paste electrode based on γ-cyclodextrin–carbon nanotube composite (γ-CD–CNT–CME) was developed for the determination of propranolol hydrochloride (PRO). The electrochemical behaviour of PRO was investigated employing cyclic voltammetry, electrochemical impedance spectroscopy and differential pulse adsorptive stripping voltammetry (DPAdSV). Surface morphology of the electrode has been studied by means of scanning electron microscopy. The results revealed that the oxidation of PRO is facilitated at γ-CD–CNT–CME. Under the optimized conditions in Britton–Robinson buffer pH 1.5, the peak currents were found to vary linearly with their concentrations in the range of 1.42 × 10−7 to 4.76 × 10−5 M. A detection limit (S/N = 3) of 4.01 × 10−8 M was obtained for PRO by means of DPAdSV. The proposed method was employed for the determination of PRO in pharmaceutical formulations, urine and blood serum samples.
