Determination of Arsenic Content in Phosphoric Acid and Ammonium Phosphate Using Atomic Fluorescence Spectrophotometry
Application research on the determination of arsenic content in phosphoric acid and ammonium phosphate using AFS-11 B atomic flu-orescence spectrophotometer.The conditions for measuring acidity,reducing agent concentration,and atomization temperature were optimized and validated using the standard curve method.The experimental results show that this method has high accuracy,stable and reliable measure-ment results,and is suitable for the determination of arsenic content in phosphoric acid and ammonium phosphate products.
