The voltammograms show single anodic and cathodic peaks. The peak separation shows that it undergoes quasi-reversible diffusion controlled controlled with slow electron transfer which is the rate determining step. The reaction takes place at pH 4 in anionic medium. Kinetic parameters such as the rate constant and diffusion coefficients are presented. The adsorption on the electrode surface made a stable modification.The anodic peak current is varied in the order F&#39;&gt;Cf &gt;Br&quot;. Energetically and analytically favourable medium for H2Q/Q redox system has been studied.</p> <p><br /> &nbsp;</p> https://journalofchemistry.org/paper/874/ Cyclic voltammetry glassy carbon electrode hydroquinone redox system
