STANDARD TEST METHODS FOR FLUORIDE ION IN WATER
|Publication Date:||3 July 1980|
|ICS Code (Examination of water for chemical substances):||13.060.50|
These methods2 cover the determination of fluoride ion in water.
Method A covers the accurate measurement of total fluoride in
water through isolation of the fluoride by distillation and
subsequent measurement in the distillate by use of the indicator
Method B covers the accurate measurement of simple fluoride ion
in water by means of an ion selective probe. With this method the
necessity for distillation is eliminated because the probe is not
affected by the interferences common
