- 中文摘要: The oscillating reaction involving organic gallic acid (GA), potassium bromate, and a metal ion complex has been reinvestigated. In contrast to other previous reports, this oscillating reaction is catalyzed by the [Fe(phen)/sub n]/sup 2+/ ion (phen=1,10-o-phenanthroline, n=1, 2, 3) rather than by the cerium ion. The characteristics of the oscillations depend on the temperature and on the concentrations of the potassium bromate, gallic acid, [Fe(phen)/sub n]/sup 2+/, and sulfuric acid. A cyclic voltam-metric study indicates that redox potential and the reversibility of the [Fe(phen)/sub n]/sup 2+/3+/ couple play a major role in catalyzing this oscillating system.
