The bacteria in the fish pond can be solved very well. Tianjin Nimo staff introduced that the use of ammonia in the fish pond is a very good advantage. Usually the gaseous ammonia is pressurized or cooled to obtain liquid ammonia. Liquid ammonia is mostly stored in pressure-resistant steel cylinders or steel tanks, and cannot coexist with acetaldehyde, acrolein, boron and other substances. Liquid ammonia is widely used in industry, is corrosive and easy to volatilize, so its chemical accident rate is very high.
Due to various reasons of the stripper itself, the imported lean liquid ammonia can be unqualified. The way to remove these elements is to contact Sinochem analysis and add samples at the bottom of the ammonia water at the lean liquid outlet (appropriate orientation such as the root of the glass level gauge). The analysis of 10E003 lean liquid import and export ammonia is inconsistent, the import is larger than the import, and the internal leakage of ammonia can be judged.
Study on the structure of the active center of nitrogenase. Nitrogenase is a combination of two transition metal-containing proteins, ferritin and molybdenum ferritin. Ferritin mainly plays the role of electron transport, while molybdenum ferritin containing two molybdenum atoms and twenty to thirty iron and sulfur atoms is the active center for complexing N₂ or other reactant (substrate) molecules and carrying out the reaction. Where. There are many opinions on the structure of the active center, but there is no final conclusion.
