1.1 Field of application This part of ISO 10359 specifies a method for the determination of inorganically bound total fluoride. The method is applicable to waste waters which are highly contaminated inorganically, with a fluoride ion concentration of more than 0,2 mg/l. 1.2 Interferences Interferences caused by certain cations (see intro- duction) or boron, which may occur in the determi- nation of fluoride, need to be eliminated by distillation.
