This standard specifies a general method for the determination of fluorine content in inorganic chemical products using the ion selective electrode method, which is suitable for the determination of fluorine ion mass concentration in the range of 0.04 μg/mL to 40 μg/mL. The standard describes in detail the preparation, reagent requirements and measurement process of the test solution. The method uses the fluorine Ion selective electrode as the indicator electrode, and cooperates with the saturated Calomel electrode for electromotive force measurement, and uses the working Linear dispersion method for quantification. The standard provides a scientific basis for the detection of fluorine content in inorganic chemical products to ensure product mass and safety.
