      The concentration of fluoride from solution of sodium fluoride of 10 mg/L could be brought down to 2 mg/L by the addition of tamarind gel alone and to 0.05 mg/L by the addition of small quantity of chloride with the tamarind gel.

    • Natural fluorinated organics in fluorite and rocks

      variety of fluorite (WF) with mass contents of 0.8, 3.7 and 60 ppb, respectively. Fluorites are found to be rich in CF4, CF2C12, CFC13 and SF6, while in granites CF4 is the only compound detectable in all samples. Interestingly, CF4 and SF6 remain undetectable in volcanites while some samples exhibit traces of CFCs.

          Phosphoric acid and sulfuric acid form calcium salts that are less soluble (more stable) than fluorite, so they will attack the fluorite to some extent even when they are dilute. This doesn't men that your fluorite will dissolve to any visible extent, but the brilliance of the surfaces might be gone after the treatment.

          • Water fluoridation Wikipedia

            All fluoridation methods, including water fluoridation, create low levels of fluoride ions in saliva and plaque fluid, thus exerting a topical or surface effect. A person living in an area with fluoridated water may experience rises of fluoride concentration in saliva to about 0.04 mg/L several times during a day.
