Formatted abstract
This paper describes the selective electrochemical determination of paracetamol (PA) in the presence of important interferent, ascorbic acid (AA) using an ultrathin electropolymerized film of 5-amino-1,3,4-thiadiazole-2-thiol (p-ATT) modified glassy carbon (GC) electrode in 0.20 M phosphate buffer solution (pH 7.20). Bare GC electrode failed to resolve the voltammetric signals of AA and PA in a mixture. On the other hand, the p-ATT modified electrode not only separated the voltammetric signals of AA and PA but also enhanced their peak currents. We achieved the lowest detection limit of 0.34 nM (S/N=3) for PA at p-ATT modified electrode.
