| 摘 要： | 在pH值为5.0的HAc-NaAc缓冲溶液中,曙红在540 nm处产生一个荧光峰,并能被ClO2氧化导致其荧光发生猝灭.通过试验确定了ClO2使曙红褪色的最佳条件,ClO2在0.042 mg/L～0.916 mg/L范围内与曙红荧光猝灭强度呈线性关系,据此建立了水中ClO2的荧光分析方法,方法检出限为0.01 mg/L.

| Abstract: | Thereisafluorescencepeak at540 nm forbromeosinin pH 5.0HAc-NaA cbuffersolution and a fluorescence quenchingtakesplace when itisoxidized by ClO 2 . The optimum conditionsforthe oxidation was studied. The intensity offluorescence quenching islinear with the concentration of ClO 2 overthe range of 0.042mg/L~ 0.916 mg/L. |
