Kjeldahl Nitrogen = Organic nitrogen + free ammonia
Nitrogen in water:
The nitrogen in water indicates organic contamination of water i.e when water is contaminated by sewage then nitrogen compounds are traced in water. We can trace the following compounds,
1) Ammonia nitrogen
2) Organic nitrogen or Albuminoid nitrogen
3) Nitrites
4) Nitrates
Nitrogen compounda are measured by colorometry
Total Kjeldahl nitrogen (TKN):
It is the sum of organic nitrogen, ammonia (NH3), and ammonium (NH4+) in the chemical analysis of soil, water and wastewater.
To calculate Total Nitrogen (TN), the concentrations of nitrate-N and nitrite-N are determined and added to the total Kjeldahl nitrogen
