Some people are comfortable with fluoride in their H20, while others would rather not have it. There is not a clear consensus on whether scientists think it's dangerous to drink this mineral. However, many people still want to know if you can remove it by boiling.
When boiling water, you're trying to remove the fluoride ion rather than the element fluorine. Because you're not dealing with the intact compound, it is impossible to boil out fluoride completely.
While boiling may not remove it, other methods actually work:
Methods That Work
To distill the water, you'll need to boil it, collect the vapor, then chill the vapor until it turns into liquid. This method involves boiling. However, boiling H20 by itself will not distill it.
Pour running water across activated alumina to capture the presence of fluoride.
Reverse osmosis involves putting water through a semipermeable membrane, which leaves ions on one side. This makes the water have a lower concentration.
Methods That Don't Work
Contrary to popular belief, some methods do not actually lower fluoride concentration. Filters and freezing don't affect the amount of fluoride in H20.
Using nonstick cookware can also increase concentration in your foods. Since the nonstick coating used is made out of a fluorine compound, it can leak into water and foods you're cooking.
Boiling actually increases the concentration of ions. However, if you boil water to condense it, you will decrease the amount of this mineral.
Try one of the above methods that will reduce the ion concentration in your H20!
