Ammonia determination (Qualitative)
All living beings have the right to live in a healthy and healthy environment. Although this is a fundamental right, it is human beings who actually destroy nature to this extent. Natural conditions have reached levels that threaten human health today. On the one hand, the efforts of industrialization and on the other hand the accelerating phenomenon of urbanization increase the use of water. On the other hand, water resources are under the threat of pollutants in many respects due to technological developments. Today, the higher the water requirement, the higher the pollution of water. As a result, the supply and cleaning of drinking and utility water has become a serious environmental problem. Water pollution control is regularly carried out by the relevant institutions and organizations. For this purpose, many sensory, physical and chemical analyzes are carried out in drinking and domestic water.
Nitrogen is an element with a natural cycle. It forms different compounds in different oxidation stages, either consumed by bacteria or chemically. The nitrogenous compounds in the organic substances which are mixed with water are converted into ammonia and then turn into nitrite and nitrate. Therefore, determination of ammonia to determine the pollution in water is the first task to be done.
Nessler reagent is used for the determination of qualitative ammonia in drinking water or drinking water. For this purpose, one of the nessler tubes is dechlorinated and the sediment is removed from the water sample, the other is put in pure water. Then a certain amount of potassium and sodium tartrate solution and nessler reagent are placed on them. After waiting for 10 minutes, the colors of the two types of water are compared. If a yellow color difference occurs in the water sample, this indicates that ammonia is present.
In the laboratories, qualitative ammonia determination studies are carried out within the scope of chemical tests. In these studies, the standards prepared by local and foreign organizations are complied with.
