Respuesta:
Ammonia is a gaseous nitrogen chemical compound whose chemical formula corresponds to NH3, and which occurs naturally when organic matter decomposes, due to the action of bacteria. As is known, it appears dissolved in wastewater in the form of ammonium ions (NH4 +).
In any case, ammonia is toxic to aquatic life, and this was, among others, one of the reasons why, in the second half of the 20th century, nitrification purification systems began to be developed, aimed at eliminating nitrogen. . Furthermore, ammonia is one of the compounds that can generate bad odors in sewage treatment plants, although to a lesser extent than hydrogen sulfide. Finally, it can also be found present in biogas, being harmful to motor generators.
Explicación:
Therefore, while in wastewater it is a matter of eliminating nitrogen to avoid eutrophication processes in the effluent basins, at the same time ammonia is directly or indirectly the origin of most of the compounds synthesized by man that contain nitrogen. , which are fundamental for Humanity, among which we can find fertilizers ... and explosives.
On October 13, 1908, the German chemist Fritz Haber discovered and patented the process to obtain nitrogen from the atmosphere and take advantage of it, since the value of nitrogen as a basic nutrient of vegetables was known. Due to the magnitude of this discovery, Haber would receive the Nobel Prize in Chemistry in 1918. Little by little the old solid forms of nitrogen to fertilize would remain in memory, among which the much scarcer nitrate of Chile stood out.
