Hi There is a difference between fluorine and fluoride. Fluorine is a
free gas and has a boiling point of about -180C but a tiny amount
dissolves in water at room temperature and it is boiled off by
distillation. Fluoride is an anion usually bound to a mineral such as
sodium or calcium, etc by strong ionic bonds and it will not boil at
100C and thus will not be in the condensate but remain in the residue.
Where did you get the information that an open distillation would not
rid the fluorine?

Hi all,
I'm trying to find the temperature at which fluoride volatizes. I've
just been told that distilling does not remove fluoride, but never
heard that before.
Supposedly reverse osmosis is the only process that does remove
fluoride from water.
Anybody know the volatization temperature of fluoride? Anybody know
if it is true that only reverse osmosis removes fluoride?
If that is true, it could be the water problem here, and why I have
to distill my water 3 times to make clear CS now. (What we have here
is naturally ocurring fluoride, not added by the water treatment plant).
