Water is an indispensable resource for human survival and daily life, known as "the source of life". People have a variety of food, only water is irreplaceable. We come into contact with water every day, turn on the faucet, and the water flows out, looking very clear and clean, but, is it really clean? According to the World Health Organization (WHO) survey, 80% of the world‘s diseases are related to poor drinking water quality! The "Drinking Water Sanitation Standards" (GB5749-2022) issued on March 15, 2022 put forward clear requirements for the quality of water. In recent years, ion chromatography has shone brightly in the field of water quality testing, and has been widely used in the analysis of samples such as drinking water, surface water, industrial wastewater, domestic water, and seawater. Ion chromatography can be used to determine a variety of ions at the same time, with high sensitivity, accuracy and rapidity. According to the method of GB/T 5750.10-2023 (Standard Test Method for Drinking Water, Part 10: Index of Disinfection By-products), after optimizing the detection conditions, an IC-2800 ion chromatograph method for the determination of ten kinds of anions in drinking water (fluoride, chloride, nitrate, sulfate, chlorate, chlorite, perchlorate, bromate, dichloroacetic acid and trichloroacetic acid) was established. The method has good repeatability and high accuracy, which can be used for reference by relevant personnel. Attachment download
