In this paper,ion chromatography is optimized for the detection of NaClO2 and KClO3 in drinking water.The results show that the concentrations of NaClO2 and KClO3 in tap water are the highest,followed by well water and the lowest in bottled water,indicating that the water treatment method had a direct effect on the production of disinfection byproducts.The optimized ion chromatography method has improved the detection sensitivity and accuracy,and has good accuracy and repeatability,which is suitable for the detection of trace disinfection by-products in water samples.
