Product Description
Sodium Persulfate Na₂S₂O₈ 99%
High-purity oxidizing agent for PCB etching, polymerization initiation, and environmental remediation applications.
Product Overview
Sodium persulfate (Na₂S₂O₈) is a powerful white crystalline oxidizing agent that generates sulfate radicals with high redox potential (E⁰ = +2.01V) through thermal, photolytic, or catalytic decomposition. This exceptional oxidizing capability makes it essential for demanding industrial applications requiring precise and efficient oxidation processes.
Core Applications
Electronics Manufacturing & PCB Processing:
- Precision micro-etching of copper layers in High-Density Interconnect (HDI) PCBs
- Creation of optimal surface roughness for enhanced plating adhesion
- Desmearing of drilled holes and removal of residual dry film
- Silicon wafer cleaning for organic contaminant removal
Polymer Synthesis:
- Efficient water-soluble free radical initiator for emulsion polymerization
- Key component in producing acrylic emulsions, PVAc emulsions, and polyacrylamide flocculants
- Broad initiation temperature range for flexible reaction control
- Essential for manufacturing superabsorbent polymers (SAP)
Environmental Remediation:
- Primary oxidant for In Situ Chemical Oxidation (ISCO) technology
- Effective degradation of persistent organic pollutants including BTEX, chlorinated ethenes, and PAHs
- Suitable for soil and groundwater contamination treatment
- Advanced oxidation processing for recalcitrant industrial wastewater
Industrial Applications:
- Low-temperature chemical polishing of stainless steel and copper alloys
- High-efficiency bleaching agent for wool and textile processing
- Oil and fat decolorization and disinfection
- Battery depolarization applications

Safety & Handling
Strong Oxidizer Hazard: Sodium persulfate is a powerful oxidizer. Store separately from combustibles, reducing agents, sulfides, and metal powders to prevent fire or explosion risks.
Decomposition Risk: Accelerated decomposition may occur under heat, impact, or contamination. Store in cool, dry, well-ventilated areas.
Personal Protection: Dust may irritate eyes, skin, and respiratory system. Use protective goggles, gloves, and masks during handling.
