GB/T 21057-2007 Inorganic chemicals for industrial use—General method for determination of fluorine content—Ion selective electrode method
Abstract
This standard specifies a general method for determining the fluoride content in inorganic chemical products — the ion-selective electrode method. This standard is applicable to the determination of fluoride content in inorganic chemical products. The standard stipulates the method for determining fluoride content. When preparing the test solution, the standard should be modified as necessary in accordance with the standards related to the product being analyzed to make it suitable for the determination of the product. This standard is applicable to fluoride ion mass concentrations in the test solution ranging from 0.04 μg/mL to 40 μg/mL.
