"GB/T 3653.1-2024 Determination of iron boron, boron content, alkali content Titrimetric method" specifies a specific method for the determination of boron content in iron boron using the alkali content Titrimetric method. The standard applies to the determination of boron content in iron boron samples in the range of 3.00% to 26.00% mass fraction. After the sample is melted by sodium carbonate or carbonic acid potassium sodium peroxide, it is leached with water to separate impurities such as iron, manganese, nickel, etc., and then titrated under controlled conditions to determine the boron content. The requirements for the use of reagents and materials are described in detail in the standard, ensuring the accuracy and repeatability of the analysis process.
