Research and exploration on the detection method of ammonia content in cement raw materials
This article mainly explores the adaptability and accuracy of potassium chloride solution extraction method and Nessler's re-agent method in detecting ammonia content in cement raw materials,and conducts third-party testing verification.The research results indicate that the potassium chloride solution extraction method is suitable for detecting ammonia content at concentrations of 0～50 mg/kg,while the Nessler's reagent method is suitable for detecting ammonia content at concentrations of 20～100 mg/kg.This study pro-vides guidance and reference for the detection of ammonia content in cement raw materials,and is of great significance for the cement industry to achieve ultra-low emissions of nitrogen oxides and ensure qualified ammonia escape.
