摘要：

It was reported that some hydroxyl/carbonyl carboxylic acids can enhance the chemiluminescence light emission intensity of Ru(phen)32+(Phen=1,10-phenanthroline) with Ce(Ⅳ). Further studies showed that methanol can also enhance the light emission intensity. In sulfuric acid medium, methanol was oxidized by eerie sulfate, the rate of oxidation depended directly on the concentration of cerium(Ⅳ) and methanol. The reaction rate changes inversely with sulfuric acid. The reaction occurs without the intermediate formation of a complex.
