Significance and Use | ||||
5.1?This test method is used for determination of the total or dissolved nitrogen content of water from a variety of natural, domestic, and industrial sources. In its most common form, this test method is used to measure nitrogen as a means of monitoring nutrient pollutant in industrial wastewater, domestic wastewater, and ambient water. These measurements may also be used in monitoring waste treatment processes. 5.2?This
test method measures oxidized ammonia and organic nitrogen (as
nitrate) and soluble nitrate simultaneously, subtracting the
nitrate + nitrite value from a non-digested sample gives total
Kjeldhal nitrogen (TKN). When using this test method:
