Interaction of luminol with phosphomolybdic, phosphovanadomolybdic and silicomolybdic acids was studied by examination of chemiluminescence spectra, measurement of ESR spectra, investigation of reaction order, and elucidation of inhibition effects. A scheme of the reaction mechanism is proposed.
A new type of voltammetry, called laser ablation voltammetry (LAV), is demonstrated by measuring voltammograms for electro-oxidation of ascorbic acid (AA) as a model reaction which is sensitive to the condition of an electrode surface. In LAV, the electrode surface is irradiated with a laser pulse at constant intervals of a few seconds during the potential scan. Because the ablation action of the...
