钢铁及合金 铁含量的测定 邻二氮杂菲分光光度法
Application Summary AI generated
This standard specifies the O-phenanthroline spectrophotometric method for determining iron content in iron, steel, and alloys. It is applied in metallurgical laboratories and quality control settings for analyzing iron concentrations in ferrous materials, particularly when high accuracy is needed for trace or low-level iron content. The method is commonly used in steel manufacturing, alloy production, and material testing to ensure compliance with compositional specifications.
