APPLICATION

General micro-etching uses sodium persulfate, which not only cleans and roughens the copper surface of the circuit, but also ensures the bonding between the graphic plating copper and the primary copper.

Sodium persulfate can be used as a bacteriostatic disinfectant and is commonly used to sterilise medical and surgical instruments.

Sodium persulfate also plays a vital role in many other industries, such as Photography industry, semiconductor industry oxidizers, and initiators etc.

Frequently Asked Questions (FAQs) About Sodium Persulfate

What is Sodium Persulfate?

Sodium persulfate is a sodium salt of persulfuric acid, a white powder that decomposes to release sulfate radicals, serving as an initiator for polymerization and an oxidant for bleaching applications.

What are the primary uses of Sodium Persulfate?

It is commonly employed in radical polymerization for resins and rubbers, textile bleaching, circuit board etching, wastewater oxidation, and cosmetic formulations for whitening.

Is Sodium Persulfate safe for industrial and consumer applications?

In its pure form, it acts as a skin and eye irritant and strong oxidizer, but when diluted or incorporated into finished products, it complies with safety standards like FDA for indirect food contact and EU cosmetics regulations.

How should Sodium Persulfate be stored to preserve efficacy?

Store in airtight containers at temperatures below 30°C in a low-humidity area, away from heat, light, and incompatible materials to prevent premature decomposition and maintain active oxygen content for up to 24 months.

Can Sodium Persulfate be used in eco-friendly processes?

Yes, it supports green chemistry by enabling low-temperature reactions that reduce energy use and by oxidizing contaminants in water treatment without persistent byproducts, aligning with sustainable manufacturing goals.

What is the difference between Sodium Persulfate and Potassium Persulfate?

Sodium persulfate offers higher water solubility for aqueous systems, while potassium persulfate provides better thermal stability; both initiate polymerization effectively but are selected based on solubility needs.

Does Sodium Persulfate have environmental impacts?

Its decomposition yields benign sulfates, minimizing long-term pollution; however, proper dosing in water treatment prevents excessive sulfate levels in effluents.
