Ammonia nitrogen determination

Determination of Ammonia Nitrogen
Determination of Ammonia Nitrogen

Nitrogen and nitrogenous substances are among the most important environmental pollutants and are one of the most important issues of environmental pollution. Nitrogenous substances are the first element of pollution in all air pollution, water pollution and solid waste management issues. Nitrogen is a nutrient necessary for the survival and reproduction of almost all living cells. In order for life to survive and for the reproduction of living things, nutrients such as nitrogen and the like must be above the required minimum amounts.

The measurement of organic and inorganic nitrogen compounds in drinking and utility water, surface water and contaminated water bodies (wastewater) is important in many respects. Detection of ammonia in drinking water indicates that feces are mixed with water. Ammonia is a colorless gas compound consisting of nitrogen and hydrogen atoms, with a sharp and foul odor. In polluted waters, ammonia nitrogen from nitrogen compounds begins to decrease, whereas nitrite and then nitrate begin to rise.

Environmental engineers generally deal with four different forms of nitrogen during their work. These are ammonia nitrogen, nitrate nitrogen, nitrite nitrogen and organic nitrogen forms. These nitrogen forms must be measured in surface waters and wastewaters.

The ammonia nitrogen is dissolved in the form of ammonium ion in water. Many methods are used to determine ammonia nitrogen in waters in competent laboratories. The most preferred methods are Nesslerization method, distillation method and ion selective electrode methods.

Ammonia nitrogen is present in various concentrations in ground and surface waters and wastewaters. Due to the development of industrialization and urbanization, the use of water is increasing. In the same way, pollutants entering the water resources have started to increase. As a result, the supply and cleaning of drinking and utility water has become a major environmental problem.

 

Authorized laboratories also carry out measurement of ammonia nitrogen within the scope of water and wastewater measurements.
