Detection of fluoride in packaged drinking water

National Food Safety Standards - Scope of Inspection Methods for Drinking Natural Mineral Water - This standard specifies the chromaticity, odor and taste, visible matter, turbidity, pH, total dissolved solids, total hardness, total alkalinity, total acidity, multi-element determination, potassium and sodium, calcium, magnesium, iron, manganese, copper, zinc, total chromium, lead, cadmium, total mercury, silver, strontium, lithium, barium, vanadium, antimony, cobalt, nickel, aluminum, selenium, arsenic, borate, metasilicic acid, fluoride Chlorides, iodides, carbon dioxide, nitrates, nitrites, carbonates and bicarbonates, sulfates, oxygen consumption, cyanide, volatile phenolic compounds, anionic synthetic detergents, mineral oils, bromates, sulfides, phosphates, total β Radioactivity, fluorine 1 "Determination method for Ra radioactivity, coliform group, fecal streptococcus, Pseudomonas aeruginosa, and Clostridium perfringens. This standard is applicable to the determination of indicators in natural mineral water for drinking. Fluoride refers to organic or inorganic compounds containing negative fluoride. Similar to other halogens, fluoride generates a single negative anion (fluoride ion F −) . Fluorine can form binary compounds with all elements except He, Ne, and Ar. From the deadly toxin sarin to the drug levofloxacin, from insoluble calcium fluoride to highly reactive sulfur tetrafluoride, all belong to the category of fluoride. On October 27, 2017, the International Agency for Cancer Research of the World Health Organization released a preliminary list of carcinogens for reference, which includes fluoride (inorganic substances added to drinking water) as a category 3 carcinogen
