• Chemical Classes: Other Classes -> Sulfur Compounds
• Canonical SMILES: [NH4+].OS(=O)(=O)[O-]
• Chemical Composition and Properties: Ammonium sulfate ((NH4)2SO4) is an inorganic sulfate salt formed by the reaction of sulfuric acid with two equivalents of ammonia. It is widely used as a fertilizer due to its nitrogen and sulfur content.
• Applications in Agriculture: Ammonium sulfate serves as a critical source of nitrogen (N) and sulfur (S) nutrients for plants. It offers several potential agronomic and environmental benefits compared to other nitrogen fertilizers, such as urea and ammonium nitrate (AN). These benefits include reduced toxicity in alkaline soils, decreased N loss via ammonia volatilization, improved soil structure in saline soils, and reduced greenhouse gas emissions.
• Enhancement of Herbicide Efficacy: Ammonium sulfate can enhance the efficacy, absorption, and translocation of herbicides such as glufosinate in various weed species. The addition of ammonium sulfate increases the efficacy of glufosinate on certain weed species by improving foliar absorption and subsequent translocation of the herbicide.
• Use in Nanotechnology: Ammonium sulfate is utilized in nanotechnology processes, such as assisting hydrothermal secondary growth of MFI nanosheet coatings. Its addition aids in preserving the orientation of deposited nanosheets and tuning membrane thickness, contributing to the separation of butane isomers.
• Everyday Applications: Ammonium sulfate finds widespread use in everyday applications due to its unique chemical and physical properties. It is commonly used in agricultural fertilizers as a source of nitrogen and sulfur nutrients, providing both quick sulfate release and season-long availability of degradable sulfur.
• Preparation and Purification: The preparation of ammonium sulfate involves treating phosphogypsum waste to obtain purified ammonium sulfate. The waste must undergo treatment or purification to remove impurities before the preparation process. Chemical analysis is conducted to assess the composition of the phosphogypsum waste.
• Utilization of Organic Waste: Organic waste generated from lysine manufacturing processes contains ammonium sulfate and various organic species. Instead of biological degradation, fermentation waste can be utilized as animal feed after desalting. The isolated salt, including ammonium sulfate, from fermentation waste is also utilized as a fertilizer.
