The use of ammonium sulfate.
Agriculture.
Ammonium sulphate is one of the widely applied to agriculture nitrogen-sulfur mineral fertilizer contains 21% nitrogen in ammonium form and 24% sulphur. Its hygroscopicity is weak, therefore, long-term storage does not cake and remains free-flowing. Provides a significant increase in yield of tea, rye, , cotton, rice, oats, sugar . Successfully competes with the best nitrogen fertilizer. Ammonium sulphate, due to the ammonium form of nitrogen that is compatible with sulfur, prevents the accumulation of nitrate in 3 times, reduces the content of radionuclides in plants in 2 times. Can be used in contaminated areas.
Used for all agricultural crops (from potatoes to citrus) on black soils and gray soils. Fertilizer has a valuable quality - lowest migration ability, since the ammonium cation is actively absorbed by the soil and it protects it from leaching. Therefore, the ammonium sulfate is recommended to make on light soils, under irrigation, i.e. where there is a potential danger of loss of nitrogen fertilizer due to the migration phenomena. Ammonium sulfate ammonium absorbed by plants. Sulfur is necessary for the supply of all crops as part of some synthesized by plants of essential amino acids.
In biochemistry reprecipitation with ammonium sulfate is a common method for purifying proteins.
The food industry is registered as a food emulsifier E517.
The means of extinguishing fires, the ammonium sulfate is used as a flame retardant.
Used in the water disinfection technology with ammoniacal, is introduced into the treated water for a few seconds before chlorine with chlorine forms chloramine - binding free chlorine, thereby significantly decreasing the formation of chlororganics harmful to the human body, reduces chlorine consumption is reduced corrosion of a pipe conduit.
In the mining industry as gel-forming component in the preventive treatment of the developed space, in the composition of the explosive substance ammonium sulphate is injected to reduce the Flammability and reduce the risk of spontaneous ignition.
Also ammonium sulphate used for the production of:
- herbicides;
- feed;
- tanning;
construction insulation.
