This standard specifies a method for the determination of ammonia nitrogen content in coking wastewater. It is suitable for the determination of ammonia nitrogen concentration in wastewater samples in the range of 10.0 mg/L to 3,500.0 mg/L. The acid formed by the reaction of formaldehyde and ammonium salt is titrated to determine the ammonia nitrogen content. The standard provides an accurate measurement method for ammonia nitrogen detection in wastewater treatment in the coking industry to ensure the compliance of wastewater treatment and environmental protection requirements.
