目的建立臭氧消毒饮用水中溴酸盐的离子色谱测定方法。方法采用离子色谱检测法,对臭氧消毒处理的水样进行了溴酸盐含量检测。结果水中溴酸盐含量在0.50~200.0μg/L条件下具有良好的线性,相关系数为0.9992,检出限为0.5μg/L,回收率为90.2~99.4%,相对误差小于5.0%。结论建立的方法可满足臭氧消毒饮用水和臭氧消毒瓶装水中溴酸盐残留量的测定,具有操作简便、快速、准确的优点。
Objective To establish an ion chromatography method for the determination of bromate in ozone disinfection drinking water. Methods The method of ion chromatography was used to detect the content of bromate in the ozone disinfection water sample. Results The bromate content in water ranged from 0.50 to 200.0μg / L. The correlation coefficient was 0.9992, the detection limit was 0.5μg / L, the recovery was 90.2-99.4% and the relative error was less than 5.0%. Conclusion The established method can meet the requirements of determination of bromate residues in ozone disinfection drinking water and ozone disinfection bottled water, and has the advantages of simple, rapid and accurate operation.
