چکیده
investigation of the redox properties of drugs and their determination are performed by electrochemical techniques. data obtained from electrochemical techniques are often correlated with molecular structure and pharmacological activity of drugs. in this regard, different modified electrodes were applied as sensors for quantification of different drugs.a nanocomposite of reduced graphene oxide-cobalt hexacyanoferrate was synthesized by a simple precipitation route. scanning electron microscopy revealed that the nanocomposite comprised nanoparticles of cobalt hexacyanoferrate attached to the reduced graphene oxide nanosheets. a nanocomposite-modified carbon paste electrode was then fabricated. it represented prominent activity toward the electrocatalytic oxidation of ascorbic acid, and the kinetics of the electrooxidation process was evaluated. finally, an amperometric method was developed for the quantification of ascorbic acid in different pharmaceutical formulations.
