Form – Crystalline Powder
Grade – ARS, ACS
Application – Oxidizing agent, polymerization initiator, PCB etching
Product Overview
Ammonium Persulfate (APS) ARS/ACS grade is a high-purity, water-soluble crystalline powder designed for precision laboratory applications. With an assay of 98% minimum, this reagent-grade oxidizer delivers consistent performance in polymerization reactions, printed circuit board (PCB) etching, and surface cleaning processes. Its strong oxidative properties make it indispensable for initiating free-radical polymerization in acrylics, vinyls, and other monomers. The ARS (Analytical Reagent Standard) and ACS (American Chemical Society) certifications ensure minimal impurities, guaranteeing reliable results in analytical procedures. The compound remains stable under normal storage conditions but decomposes upon heating, releasing oxygen and forming ammonium sulfate. Its white, odorless appearance and high solubility in water (582 g/L at 20°C) allow for easy handling and precise dosing in aqueous systems. The product is packaged in airtight containers to prevent moisture absorption and maintain purity over extended shelf life.
FAQs
1. What is the shelf life of Ammonium Persulfate ARS/ACS grade?
When stored in a cool, dry place in its original sealed container, the product maintains its specified purity for 24 months from the date of manufacture.
2. Can this be used as a substitute for potassium persulfate?
Yes, it can replace potassium persulfate in most applications, though you may need to adjust concentrations due to differences in molecular weight and solubility.
3. What safety precautions should be taken when handling this chemical?
Wear nitrile gloves, safety goggles, and a lab coat. Avoid contact with organic materials, metals, or reducing agents to prevent violent reactions.
4. Does this product require special disposal methods?
Neutralize with sodium bisulfite solution before disposal according to local hazardous waste regulations. Never dispose of untreated in drains.
5. How does the ARS grade differ from the ACS grade in this product?
The ARS grade meets Indian analytical standards while ACS grade complies with American Chemical Society specifications. Both offer comparable purity for most lab applications.
