ActiveMethods forchemical analysis of iron，steel and alloy--The chlorophosphonago mA photometric method for the determination of cerium content after extraction separation
钢铁及合金化学分析方法 萃取分离-偶氮氯膦mA光度法测定铈量
Application Summary AI generated
This standard specifies a photometric method using chlorophosphonago mA to determine the cerium content in iron, steel, and alloys after extraction separation. It is applied in metallurgical laboratories and quality control settings for the chemical analysis of ferrous materials, particularly when precise measurement of rare earth element cerium is required. The method is used to ensure material composition meets specified standards in steelmaking and alloy production.
