Applications:
An excellent nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops, can make branches and leaves grow exuberant, improve fruit quality and yield, enhance crop resistance to disaster, can be used as base fertilizer, topdressing and seed fertilizer. It can react with salt to produce ammonium chloride, react with aluminum sulfate to produce ammonium alum, and produce refractory materials together with boric acid. The addition of electroplating solution can increase the conductivity. It is also a catalyst for food sauce color, a nitrogen source for yeast cultivation in fresh yeast production, an acid dye dye aid, and a leather deashing agent. In addition, also used in beer brewing, chemical reagents and battery production. Another important role is the mining of rare earth, mining with ammonium sulfate as raw material, using the form of ion exchange to exchange the rare earth elements in the ore, and then collect leaching solution to remove impurities, precipitation, pressing, burning into rare earth ore, every mining production of 1 ton of rare earth ore needs about 5 tons of ammonium sulfate.
Biological use are many, many process used for protein purification, because ammonium sulphate belongs to an inert material, not easy to react with other biological active substances, in the purification process can protect protein activity to a great extent, on the other hand, soluble ammonium sulfate is wonderful, can form high salt environment, for protein precipitation to prepare high salt and purification of follow-up.
