What Does TKN Stand For?

TKN stands for Total Kjeldahl Nitrogen

Total Kjeldahl Nitrogen (TKN) is a measurement used in environmental science and aquatic chemistry to quantify the total concentration of nitrogen in a sample, including both organic and inorganic forms. It is instrumental in assessing water quality, particularly in wastewater treatment and agricultural runoff, as it provides insights into nitrogen availability and potential impacts on ecosystem health. The TKN analysis involves the digestion of the sample to convert nitrogenous compounds into ammonia, which is then measured to determine the total nitrogen content.
