Аннотация
Here we are presenting complete electrochemical studies on redox activities of 1,2-dinitrobenzene (DNB) in the presence of antioxidants–quercetin, morin, rutin, ascorbic acid and β-carotene. Bimolecular rate constants (k2), antioxidant activities (Ka) and diffusion coefficients (Do) were evaluated from changes in voltammeric responses and electrochemical parameters in the presence of antioxidant’s concentrations. Theoretical charge calculations by PM3 parameterization were done which further justified our experimental electrochemical work and proposed scavenging mechanism. Present findings were also compared in details with our previously reported studies on 1,3- and 1,4-dinitrobenzene systems for their interactions with antioxidants.
