In recent years, ion chromatography has been widely used in the analysis of drinking water, surface water, industrial wastewater, domestic water and seawater samples. Ion chromatography can simultaneously determine a variety of ions, with high sensitivity, accuracy, rapidity and other characteristics, and has good working efficiency. In this paper, with reference to the standards of "GBT5750.5-2006 Standard Inspection Method for Drinking Water, Inorganic Non-Metallic Index" and "GBT5750.10-2006 Standard Inspection Method for Drinking Water, Index of Disinfection By-products", a method for the simultaneous determination of fluoride ions (F-), bromate ions (BrO3-), chloride ions (Cl-), nitrite ions (NO2-), bromine ions (Br-), nitrate ions (NO3-), phosphate ions (PO43-) and sulfate ions (SO42-) by one injection of IC-2800 ion chromatography was established for the reference of relevant personnel.
