GB/T 35925-2018 "Determination of Impurities Fluoride Ions in Water-soluble Chemicals" Ion chromatography specifies a method for the determination of fluoride ions in water-soluble chemicals using Ion chromatography. This standard applies to water-soluble chemicals with a fluoride ion content of not more than 400 mg/kg, and the quantification limit is 0.02 mg/kg for organic chemicals and 4.0 mg/kg for inorganic chemicals, respectively. This standard does not apply to insoluble chemicals and chemicals containing fluoride main components, providing an important detection method standard for the industry.
