GB/T 6730.89-2024 "Iron Ore, Determination of Thorium Content, Arsenazo ⅲ Spectrophotometric method, spec-trophotometry" standard specifies a method for the determination of thorium content in iron ore by arsenazo ⅲ Spectrophotometric method, spec-trophotometry. It is suitable for the determination of thorium content in natural iron ore, iron concentrate, sinter, pellet. Measurement range is 0.005% to 0.60% mass fraction. The standard details the dissolving, extraction and color development process of the sample. The mass fraction of thorium is calculated by measuring the Absorbance at a wavelength of 660nm to ensure the accuracy and Reliability of the analysis results.
