[目的]调查广州市售瓶装饮用水溴酸盐(BrO3-)、亚氯酸盐(ClO2-)、氯酸盐(ClO3-)这3种消毒副产物(disinfection by-products,DBPs)的含量状况。[方法]用离子色谱仪同时测定这3种消毒副产物含量,选用Dionex Ionpac AS19-2mm型分析柱,RFIC淋洗液在线发生器在线生成KOH淋洗液进行梯度淋洗,抑制型电导检测器,进样体积为200μl。[结果]广州市售瓶装水中BrO3-、ClO2-、lO3-含量均未超标,但部分瓶装矿泉水中BrO3-含量较高。[结论]应关注瓶装矿泉水中BrO3-、ClO2-、lO3-的日常监测。
[Objective] To investigate the content of three kinds of disinfection by-products (DBPs) such as bromate (BrO3-), chlorite (ClO2-) and chlorate (ClO3-) situation. [Method] The contents of these three kinds of disinfection by-products were determined simultaneously by ion chromatography. Dionex Ionpac AS19-2mm analytical column was used. The RFIC eluent online generator generated KOH eluent gradient elution. The inhibitory conductivity detector , Injection volume of 200μl. [Result] The contents of BrO3-, ClO2- and lO3- in bottled water in Guangzhou were not exceeded, but the content of BrO3- in some bottled mineral water was higher. [Conclusion] The daily monitoring of BrO3-, ClO2- and lO3- in bottled mineral water should be concerned.
