Персульфат аммония APS Персульфат диаммония CAS 7727-54-0

Tree Chem Ammonium Persulfate (APS) is an inorganic peroxide that serves as a strong oxidizing agent and free-radical initiator. With high assay, low chloride and heavy metal impurities, and high active oxygen content (≥6.9%), it provides consistent performance and stability in polymerization of monomers such as acrylonitrile, styrene, and butadiene.

Besides polymerization, APS is also utilized in electronic circuit cleaning, textile desizing, soil remediation, and surface treatment. Its decomposition produces sulfate ions without harmful residues, making it an environmentally compatible alternative to chlorine-based oxidants.

Технические характеристики

Приложения

Water and Environmental Treatment

• Ammonium Persulfate is extensively used as a powerful oxidizing agent in various water and environmental treatment processes. It generates sulfate radicals (SO₄•⁻), which can effectively break down complex organic pollutants such as phenols, dyes, and petroleum residues. These radicals react rapidly and leave no secondary contamination, making Ammonium Persulfate a preferred reagent for advanced oxidation processes (AOPs).
• In groundwater and soil remediation, Ammonium Persulfate provides an efficient way to decompose long-chain hydrocarbons and chlorinated organic compounds. It is particularly effective for treating contaminated industrial sites and petroleum spill areas where traditional oxidants are less efficient. Its ability to operate under a wide pH range and its low toxicity make it environmentally compatible for sustainable remediation projects.

Polymer and Resin Production

• In the polymer industry, Ammonium Persulfate serves as a free-radical initiator for emulsion, suspension, and solution polymerization. It initiates polymerization of monomers such as styrene, acrylonitrile, acrylates, and butadiene, ensuring precise molecular weight control and uniform particle size. Its high thermal stability allows consistent polymerization at elevated temperatures without undesired side reactions.
• Ammonium Persulfate is also widely employed in the production of synthetic latexes and coatings. It provides controlled polymer chain initiation that improves the mechanical strength, gloss, and film-forming properties of polymer emulsions. This makes it an essential additive in the manufacture of synthetic rubber, acrylic emulsions, adhesives, and waterborne paints.

Textile and Paper Industries

• In the textile sector, Ammonium Persulfate is commonly used for oxidative desizing and bleaching. It removes natural impurities, waxes, and pigments from cotton and polyester fibers without causing fabric damage. This process enhances fabric brightness, improves dye uptake, and reduces the need for harsh chlorine-based bleaching agents.
• In the paper industry, Ammonium Persulfate functions as a pulp brightener and deinking agent. It enhances the whiteness of recycled paper by oxidizing residual ink particles and cellulose impurities. It also improves paper strength and surface uniformity, making it suitable for high-quality printing and packaging papers.

Electronics and Metal Surface Treatment

• Ammonium Persulfate is a clean etchant and surface cleaner for the electronics industry. In PCB manufacturing, it selectively dissolves copper layers to produce clean circuit patterns with precise edges. Compared with ferric chloride and cupric chloride etchants, Ammonium Persulfate offers better bath stability and leaves minimal residue.
• It is also applied in semiconductor cleaning and metal finishing processes. Ammonium Persulfate removes oxide scales and organic residues from aluminum, copper, and stainless steel surfaces without pitting or corrosion. This ensures optimal adhesion and surface quality for subsequent electroplating or coating processes.

Cosmetics and Personal Care

• Ammonium Persulfate is used in hair bleaching and coloring formulations as an oxidizing component. It enhances the decomposition of melanin in hair, enabling efficient lightening when combined with hydrogen peroxide. The synergy between Ammonium Persulfate and other persulfates ensures faster bleaching while maintaining manageable exothermic control.
• In addition, controlled formulations of Ammonium Persulfate are applied in cosmetic-grade depilatory and whitening products. It contributes to oxidative reactions that help remove pigment or protein-based materials on skin or hair while adhering to cosmetic safety standards.

Oilfield and Chemical Applications

• In the oilfield sector, Ammonium Persulfate acts as a polymer gel breaker in hydraulic fracturing operations. After fracturing, it decomposes polyacrylamide-based gels by generating radicals that cut long polymer chains, thus reducing viscosity and facilitating fluid flowback. This ensures better well productivity and reduced formation damage.
• Ammonium Persulfate is also used as an oxidant in chemical synthesis and catalyst regeneration. It promotes clean oxidation of organic compounds and assists in reactivating deactivated catalysts by removing carbonaceous deposits. Its versatility makes it suitable for fine chemical manufacturing and redox reaction systems.

Emerging Applications

• In advanced materials research, Ammonium Persulfate is a key oxidant in the synthesis of conductive polymers such as polyaniline, polypyrrole, and polythiophene. It enables oxidative polymerization that produces highly conjugated chains with excellent electrical properties.
• It is also being studied for applications in nanomaterial surface modification и environmental catalysis, where its controlled decomposition produces reactive radicals capable of introducing functional groups on particle surfaces. This expanding role highlights Ammonium Persulfate’s importance in both traditional and emerging industrial fields.

Хранение и обработка

• Store in dry and sealed containers to prevent moisture absorption and decomposition.
• Avoid sunlight, heat, and humidity. Keep away from direct radiation or ignition sources.
• Prevent contamination with impurities such as organic matter, iron, and reducing agents that may trigger decomposition.
• Handle carefully during storage and use to avoid friction, impact, and contact with incompatible materials.
• Avoid contact with skin, eyes, or clothing, as moist APS has mild bleaching and corrosive effects.
