Electrochemical study of catechol–boric acid complexes

The electrochemical behavior of catechol–boric acid complexes in aqueous solutions has been studied using cyclic voltammetry and steady-state voltammetry with a rotating disk electrode. Different patterns of reactivity and various kinetic pathways have been examined. Based on a CE mechanism, the dissociation constant and homogeneous rate constants of complex formation and dissociation were estimated for each pathway by comparing the experimental cyclic voltammograms with the digitally simulated results. Also, the effects of pH and substituted groups on dissociation constants and reaction kinetics were studied.
