The adsorption of Ru(bpy)32+ on a glass carbon electrode has been investigated by cyclic voltammetry (CV) and electrochemiluminescence (ECL). Experimental results show that the adsorption of Ru(bpy)32+ on the surface of glass carbon electrode was obviously affected by the concentration of Ru(bpy)32+ and immersion time. The luminescent intensity decreases in the repetitive CV scan caused by the divorce of the oxidation product, , which made a great intensity change in the initiatory of ECL measurement.

Key words: electrochemiluminescence, Ru(bpy)32+, glass carbon electrode, adsorption
