2. Nitrate test - Wikipedia

   en.wikipedia.org/wiki/Nitrate_test

   A common nitrate test, known as the brown ring test [2] can be performed by adding iron (II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the presence of the nitrate ion. [3]

   Gunshot residue. Gunshot residue ( GSR ), also known as cartridge discharge residue ( CDR ), gunfire residue ( GFR ), or firearm discharge residue ( FDR ), consists of all of the particles that are expelled from the muzzle of a gun following the discharge of a bullet. It is principally composed of burnt and unburnt particles from the explosive ...

4. Denitrification - Wikipedia

   en.wikipedia.org/wiki/Denitrification

   Denitrification is a microbially facilitated process where nitrate (NO 3−) is reduced and ultimately produces molecular nitrogen (N 2) through a series of intermediate gaseous nitrogen oxide products. Facultative anaerobic bacteria perform denitrification as a type of respiration that reduces oxidized forms of nitrogen in response to the ...

5. Griess test - Wikipedia

   en.wikipedia.org/wiki/Griess_test

   The Griess test is an analytical chemistry test which detects the presence of nitrite ion in solution. One of its most important uses is the determination of nitrite in drinking water. The Griess diazotization reaction, on which the Griess reagent relies, was first described in 1858 by Peter Griess. [1] [2] The test has also been widely used ...

6. Nitrification - Wikipedia

   en.wikipedia.org/wiki/Nitrification

   Nitrification. Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite. Nitrification is an important step in the nitrogen cycle in soil. The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.
