【Abstract】 The electrochemiluminescence (ECL) of the luminol in aqueous alkaline solu tion has been studied using cyclic voltammetry, potential step tecdrique and time resolved UV/Vis spectroscopy. The results of the electrochemical experimens showed that the ECL of the luminol can carry out in the potential region of oxygen adsorption also and lead us suggest a new light-endtting pathway for the bonol on which the reaction between some of the luminol radical Anons and the adsorbed superokide radical sndtaneously gener ated in the anodic oxidation process yields excited 3-drinophthalate, the light emitting species. The results of the time resolved spectroscopic experiments manifested that the formation of the polymeric film produced by the luminol radical anions is one of important faetors decreasing the ECL of the luminol.更多还原
