ASTM C25-19 is a standard test method for the photometric determination of manganese (Mn), phosphorus (Ph), and iron (Fe) in limestone, quicklime, and hydrated lime. The method involves dissolving a sample of the material in acid and reacting it with specific reagents to form colored complexes, which are measured using a photometer. This analysis provides valuable information for assessing the quality of these materials for various applications.
