Scope
This standard specifies the ion-selective electrode method for the determination of fluoride in fertilizers.
This standard is applicable to the determination of acid-soluble fluoride (calculated as F) in phosphorus-containing fertilizers.
The detection limit of this method is 2.5 μg, and the linear range is 0~20 μg/mL.
