In the production process of refining catalysts and molecular sieves, reactive or toxic ammonia water and organic amine templates (such as methylamine, ethylamine, ethanolamine,N-methyldiethanolamine) need to be used as structural directing agents for synthesizing phosphorus aluminum system zeolites. If these compounds are directly discharged, they will cause environmental pollution and affect the development of green chemicals. Therefore,establishing a method for analyzing the content of ammonia and fatty primary amines in water is of great significancefor monitoring the discharge of catalyst production wastewater and environmental protection.
