Total Kjeldahl Nitrogen. There is no MCl for total kjeldahl nitrogen. This parameter is used to measure the total amount of organic nitrogen and is typically used for surface water and groundwater investigations associated with domestic or agricultural contamination.
Total Kjeldahl Nitrogen. The sum of organic nitrogen and ammonia in a water body. Measured in milligrams per liter (mg/L). High measurements of TKN typically results from sewage and manure discharges to water bodies.
Total Kjeldahl nitrogen. An analyticalmethod for determining total organic nitrogen andammonia.
Total Kjeldahl nitrogen. An oxidative procedure that converts organic nitrogen forms to ammonia by digestion with an acid, catalyst, and heat.
Total Kjeldahl nitrogen. An analytical method for determining total organic nitrogen and ammonia.
