摘要
合成了含羟基苯并吲哚并研究其对过氧化氢的荧光响应,考察了溶剂种类及p H值等因素对检测体系的影响﹒在最佳实验条件下,过氧化氢将引发580 nm处荧光信号蓝移至560 nm处,且其荧光强度随过氧化氢浓度的增加而增强,线性范围为0.1~1.2 mmol/L,检出限为72 mol/L,探针响应不受其它干扰物的影响﹒该方法可用于消毒液及自来水样品中过氧化氢的准确测定﹒
Benzoindoles containing hydroxyl （DHB） was synthesized and applied for the fluorescence response to hydrogen peroxide （H2O2）, and the effects of solvents and pH values were studied on the detection system. Under the optimum conditions, the increased concentration of H2O2 caused the fluorescence signal of DHB shifted from 580 nm to 560 nrn, and that at 560 nm enhanced gradually in the linear range of 0.1 mM to 1.2 mM with detection limit of 0.72 M. This method can be used for the determination of trace concentration of H2O2 in disinfectant and tapwater samples with satisfactory results and good selectivity over other interference.
