Scope

This part of GB/T 13025 specifies the methods for the determination of potassium ferrocyanide in edible salt by the ferrous sulfate method and the pyridine-pyrazolone method. The ferrous sulfate method in this part is applicable to the determination of potassium ferrocyanide in edible salt, and the detection range is 4μg/50mL～100μg/50mL (calculated as [Fe(CN)6]4-). The pyridine-pyrazolone method is suitable for the quantitative determination of trace amounts of potassium ferrocyanide in edible salt and salt for food processing, with a detection range of 0-7.0 μg/g (calculated as [Fe(CN)6]4-).
