ELECTROGENERATEDCHEMILUMINESCENCE BEHAVIOR OF A Ru(bpy)_3~(2+) SYSTEM ON A PARAFFIN-IMPREGNATED GRAPHITE ELECTRODE

摘要

The amperometric and ECL behaviours of Ru(bpy)_3~(2+)/C_2O_4~(2-) system on PIGE were carefully investigated by CV, CSW and chronoamperometric techniques. Depending on its complicated ECL behaviour, possible mechanisms for EP1 and EP2 were speculated. From the amperometric and ECL efficiency results, it can be concluded that the low-cost PIGE exhibited good ECL-responsibility and sensitivity and presented excellent stability in aqueous solution.
