scope:
Specifies a method for the determination of nitrogen present in water in the form of free ammonia, ammonium, nitrite, nitrate and organic compounds capable of conversion to nitrogen dioxide under the oxidative conditions described. Determination is carried out instrumentally using chemiluminescence detection. Dissolved nitrogen gas is not determined by this method. This method is applicable to the analysis of natural freshwater, seawater, drinking water, surface water, waste water and treated sewage effluent.
