Ammonium Persulfate (APS), with the chemical formula (NH₄)₂S₂O₈, is a white crystalline solid with a molecular weight of 228.20. As a strong oxidizer, it is highly soluble in water, releasing substantial heat during dissolution. This property makes it an efficient and stable oxidizer and initiator in numerous chemical reactions. Leveraging these characteristics, Ammonium Persulfate finds extensive applications across industries such as chemicals, environmental protection, new energy, and agriculture. The following discusses the primary functions and uses of Ammonium Persulfate (APS).
The core utility of Ammonium Persulfate stems from its strong oxidizing power. As a highly effective oxidizer, it supplies active oxygen and participates widely in various redox reactions, particularly excelling in free radical generation and polymer polymerization. For example, in polymerization reactions, APS acts as an initiator, decomposing to produce sulfate radicals (SO₄⁻・). These radicals trigger monomer polymerization, gradually forming polymer chains—making it a critical raw material in industries such as synthetic rubber, plastics, and coatings.Additionally, in catalyst regeneration, Ammonium Persulfate’s oxidizing ability effectively removes impurities from catalyst surfaces, extending catalyst service life and ensuring efficient catalytic reactions.
In environmental protection, Ammonium Persulfate delivers outstanding performance. Its powerful oxidation capacity makes it a vital tool in wastewater treatment, especially for non-biodegradable organic pollutants. Through oxidative degradation, complex organic molecules are broken down into simpler small molecules, purifying water quality. Furthermore, it is used in soil remediation to oxidize and remove harmful substances, improving soil conditions. These applications not only highlight APS’s technical advantages but also provide robust support for environmental protection.
With the rapid development of new energy technologies, Ammonium Persulfate has increasingly found applications in new materials and energy sectors. For instance, in lithium-ion battery production, it is used for surface treatment of electrode materials to enhance conductivity and stability. It also plays a key role in preparing fuel cell catalysts, improving energy conversion efficiency. These applications demonstrate APS’s potential in driving the new energy industry.
Agriculture is another significant application domain for Ammonium Persulfate. As a pesticide intermediate, it is involved in synthesizing various fungicides and insecticides. Its strong oxidizing properties effectively inhibit pest and disease propagation, protecting crop health.
