In general, nitrogen is present in natural water in the forms of organic nitrogen, ammonia, nitrate, and nitrite.
In general, direct manual determination of low concentrations of ammonia is confined to drinking waters, clean surface or groundwater, and good-quality nitrified wastewater effluent. In other instances, and where interferences are present or greater precision is necessary, a preliminary distillation step (4500-nh 3b) is required.
Selection of method the two major factors that influence selection of the method to determine ammonia are concentration and presence of interfer-ences. In general, direct manual determination of low concen-trations of ammonia is confined to drinking waters, clean surface.
