Description / Abstract: The method is based on developing a potential difference between the measuring electrode and the reference electrode, when a fluoride ion-selective electrode comes into contact with an aqueous solution containing fluoride ions. On certain assumptions specified, the method will no longer refer to activities, but to fluoride ion concentration. The method is directly suitable for measuring fluoride concentrations from 0,2 mg/l to 2,0 g/l.
