摘要：

The electrogenerated chemiluminescence (ECL) that arises upon sweeping or stepping the potential of a highly oriented pyrolytic graphite (HOPG) electrode to positive potentials in a solution containing tripropylamine after immersion of the HOPG in Ru(bpy)3(2+) solutions followed by thorough washing is ascribed to strong adsorption of Ru(bpy)3(2+) on the graphite surface. The dependence of the observed ECL emission on Ru(bpy)3(2+) concentration (over a range of 60-300 nM) was used to find the adsorption isotherm. Similar adsorption and ECL was found with platinum and gold electrodes.
