摘要: The adsorption of iodine and iodide anions on a Pt/Pt electrode (0.5 M H2SO4 as supporting solution) is compared using potentiodynamic galvanostatic charging curves, transients the current open-circuit potential (OCP), analytical measurements. Variations in charge OCP during obey relationships derived for strong neutral species ions hydrogen with formation irreversibly adsorbed atoms. main product I2 I– chemisorption acid solutions However, occurs noticeable amounts above monolayer form that undergo electrodesorption cathodic polarization to potentials beginning adsorption. In presence atoms, zero total oxygen region.
