Description
Additional information

Ammonium sulfate, also known as ammonium sulfate, is the earliest nitrogen fertilizer to be produced and used both domestically and internationally. Generally, it is regarded as a standard type of nitrogen fertilizer, with its nitrogen content ranging from 20% to 30%.

Ammonium sulfate is mainly used as fertilizer and is suitable for various soils and crops. It can also be used in textile, leather, medicine, and other fields. A good nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops, can promote vigorous growth of branches and leaves, improve fruit quality and yield, enhance crop resistance to disasters, and can be used as base fertilizer, topdressing, and seed fertilizer. It can undergo double decomposition reaction with table salt to produce ammonium chloride, react with aluminum sulfate to produce ammonium alum, and together with boric acid, produce refractory materials. Adding to the electroplating solution can increase conductivity. It is also a catalyst for food coloring, a nitrogen source for cultivating yeast in fresh yeast production, an acid dye dyeing aid, and a leather deliming agent. In addition, it is also used in beer brewing, chemical reagents, and battery production. Another important role is to extract rare earth elements. Ammonium sulfate is used as the raw material for mining, and ion exchange is used to exchange the rare earth elements in the soil. The leaching solution is then collected, precipitated, pressed, and burned to form the rare earth ore. Approximately 5 tons of ammonium sulfate are required for each ton of rare earth ore produced during mining.

There are also many biological applications, mostly used in protein purification processes, because ammonium sulfate is an inert substance that is not easily reacted with other bioactive substances, and can protect protein activity to the greatest extent during the purification process. In addition, ammonium sulfate has excellent solubility and can form a high salt environment, preparing for protein precipitation and subsequent high salt purification. There is a significant difference in the solubility of ammonium sulfate at zero and room temperature of 25 degrees. The following are the molar concentrations of ammonium sulfate with different saturation levels at two temperatures.
