Chemex (surface water) Orion ISE (F)
Chemex, surface water; ion-selective electrode (fluorine). The fluoride was measured using a model 401 Orion specific ion meter with an Orion fluoride electrode.
Fluoride in water samples was determined using an Orion fluoride electrode and a model 401 Orion specific ion meter. Prior to measurement, an aliquot of the sample was mixed with an equal volume of a modified TISAB solution (total ionic strength adjustment buffer). The modification consisted of adding 60 ml 8 M KOH solution to the buffer. This permitted the re-analysis of fluoride in acidified water samples when required. When this analysis was required, acidified standard solutions were used for calibration.
