Περιγραφή προϊόντος
ACS Grade Sodium Persulfate Na₂S₂O₈ for Water Treatment
High-purity ACS Grade Sodium Persulfate (Na₂S₂O₈) designed specifically for water treatment applications. Free samples available for qualified customers.
Product Overview
Ammonium persulfate serves multiple industrial applications including battery manufacturing, polymerization initiation, fiber desizing, and surface treatment for metals and semiconductors. It is also utilized in printed circuit board etching, oil reservoir fracturing, flour and starch processing, oil and fat industries, and photographic applications.

Chemical Properties
Peroxydisulfate contains peroxide groups and functions as a strong oxidizing agent capable of oxidizing Mn²⁺ to MnO₄⁻. Ammonium persulfate is produced through electrolysis of ammonium bisulfate aqueous solutions.
Dissolution in water follows the equation:
S₂O₈²⁻ + 2H₂O ⇌ 2HSO₄⁻ + H₂O₂
The resulting solution contains ammonium ions, peroxydisulfate ions, hydrogen sulfate ions, and sulfate ions. The hydrolysis process creates an acidic solution, with nitric acid addition inhibiting the forward reaction.
Primary Applications
This high-purity Ammonium Persulfate (APS, (NH₄)₂S₂O₈) serves as a powerful oxidizing agent and sulfate free radical source. With guaranteed purity of 99% or higher, this white crystalline solid represents the industry standard for reliability and performance in precision applications.
Polymerization Initiator
The 99% purity level is essential for polymerization applications, as trace impurities can act as inhibitors or chain-transfer agents, leading to unpredictable reaction kinetics and suboptimal polymer properties. This APS is the preferred initiator for synthesizing high-molecular-weight polymers via free-radical mechanisms.
- Thermally decomposes to generate sulfate radical anions (SO₄*⁻)
- Efficiently initiates polymerization of acrylamide, vinyl acetate, styrene, and acrylates
- Water solubility enables homogeneous initiation in emulsion and solution polymerization
- Critical for production of polyacrylamide flocculants, electrophoresis gels, adhesives, paints, and specialty plastics
PCB (Printed Circuit Board) Etchant
In electronics manufacturing, high-purity APS solutions provide precision micro-etching and surface preparation for multi-layer and high-density interconnect boards.
- Cleans and micro-etches copper surfaces to remove oxides
- Creates optimal microscopically roughened topography for enhanced adhesion
- Offers superior etching uniformity and controlled etch rates
- Simplifies waste treatment with decomposition products primarily being ammonium sulfate
- Ensures clean, well-defined circuit traces without undercutting
As your dedicated supplier, we provide consistent quality, batch-to-batch traceability, secure supply chain management, and comprehensive technical support to optimize your manufacturing processes.
