| Abstract | Paired (simultaneous) electrochemical processes can increase energy savings in selected cases by using the reactions at both electrodes of an electrochemical cell to perform a desired process, as is the case in the commercially successful chlor-alkali process. In the demonstration described herein, simultaneous blue electrochemiluminescence (ECL) is obtained with luminol in a basic medium in a divided electrochemical cell. ECL is obtained in the anolyte through the direct oxidation of luminol, the reaction products of which interact with H[subscript 2]O[subscript 2] in the vicinity of the electrode to yield an excited emitting species. ECL is also obtained in the catholyte through an indirect, mediated process involving the initial reduction of ClO[subscript 2] - to ClO-, which then reacts with luminol and H[subscript 2]O[subscript 2] to produce the excited emitting species. The co-reactant (H[subscript 2]O[subscript 2]) is needed to complete the reaction sequences in both compartments of the cell. This ECL phenomenon is visible to the naked eye in a darkened room at a distance of up to 5 m. (Contains 4 figures.) (As Provided). |
