| Summary | This standard specifies the gas phase molecular absorption spectrometry method for the determination of ammonia nitrogen in water. This standard is applicable to the determination of ammonia nitrogen (measured in N) in surface water, groundwater, domestic sewage, industrial wastewater and seawater. The detection limit of the method is 0.02 mg/L, and the lower determination limit is 0.08 mg/L. |
