Ammonium sulfate is an excellent nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops, can make leaves grow strong, improve fruit quality and yield, and enhance crop resistance to disasters, can be used for basal, top dressing and fertilizer. With the salt decomposition reaction to produce ammonium chloride, and aluminum sulfate role in the formation of ammonium alum, and boric acid, etc. Ammonium Sulfate together with the manufacture of refractories. Addition to the plating solution can increase the conductivity. Also the food sauce color of the catalyst, the production of fresh yeast yeast yeast nitrogen source, Ammonium Sulfate acid dye dyeing dye, leather deodorant. In addition, also used for beer brewing, chemical reagents and battery production. There is an important role is the exploitation of rare earth, mining ammonium sulfate as raw materials, Ammonium Sulfate the use of ion exchange in the form of rare earth elements in the mineral exchange, and then extract leaching solution impurities, precipitation, pressing, after burning into rare earth ore, 1 ton of rare earth ore about 5 tons of ammonium sulfate.
Biological use is also a lot, and more for the protein purification process, because ammonium sulfate is an inert substance, not easily react with other bioactive substances in the purification process to maximize the protection of protein activity, in addition, the solubility of ammonium sulfate Well, Ammonium Sulfate can form a high salt environment, for protein precipitation and follow-up high salt purification to prepare. Ammonium sulfate in the zero and room temperature 25 degrees of solubility are quite different, the following is the ammonium sulfate at two temperatures at different temperatures of the molar concentration.
Ammonium sulfate referred to as ammonium sulfate, colorless crystal or white particles, odorless, 21% nitrogen, soluble in water, easy to moisture, easy to store and use, Ammonium Sulfate insoluble in ethanol and acetone, low toxicity, irritating. But the wet and humid season of hygroscopicity, moisture consolidation into a block, so when stored, also pay attention to ventilation and dry. Heated to 513 ℃ above fully decomposed into ammonia, nitrogen, Ammonium Sulfate sulfur dioxide and water. With the role of alkaloids are released ammonia. And barium chloride solution reaction to generate barium sulfate precipitation. Can also make the protein salting out.
Ammonium sulfate mainly acts on fertilizers, chemicals, agriculture, crops, rare earth, textile, leather, medicine, soil and so on.
1, for fertilizer, suitable for a variety of soil and crops; can make strong growth of foliage, improve fruit quality and yield, and enhance crop resistance to disasters.
2, for textile, leather, medicine and other aspects; acid dye dyeing dye, leather deodorant.
3, consumption of ammonium sulfate by adding ammonium sulfate industrial distilled water, adding arsenic removal agent and in addition to heavy metal agent for solution purification, Ammonium Sulfate filtration, evaporation and concentration, cooling crystallization, centrifugal separation of dry system. Used as a salt additive, do dough conditioner, yeast nutrient.
4, applied to biochemical, Ammonium Sulfate salting out the commonly used salt, salt can be the initial fermentation from the upstream products such as separation and purification of protein and so on.
5, the exploitation of rare earth, mining ammonium sulfate as raw materials, Ammonium Sulfate the use of ion exchange in the form of rare earth elements in the exchange of minerals, and then extract the leaching solution after a simple separation of dried earth into rare earth ore, each production of 1 ton of rare earth ore about 5 tons Ammonium sulfate.
