Abstract: An equation for quasi-steady-state linear potential sweep voltammetric current influenced by migration was presented.Aseries of ions with various charges, such as Fe(CN)64-, Fe3+, Ru(bpy)32+ and FeCp20, was employed to explore the migrational effects on voltammogram in different values of supporting electrolyte concentration.The theoretical predicated limiting currents are in good agreement with the experimental results.
