Description

Potassium Peroxymonosulfate is a powerful inorganic oxidizer, commercially significant for its stability and broad-spectrum reactivity. Its primary value lies in its ability to generate highly reactive sulfate radicals, making it a versatile and effective agent for oxidation and disinfection processes. This compound is essential for industries requiring advanced oxidation technologies, water treatment, and specialty chemical synthesis.

Application

• Advanced Oxidation Processes (AOPs): A key component in generating sulfate radicals for the degradation of persistent organic pollutants, pharmaceuticals, and microplastics in industrial and municipal wastewater.
• Pool & Spa Treatment: Used as a non-chlorine shock oxidizer to break down organic contaminants, chloramines, and restore water clarity.
• Pulp & Paper Bleaching: Employed as an environmentally friendly bleaching agent for mechanical and chemical pulps.
• Organic Synthesis: Serves as a selective oxidizing agent in the synthesis of fine chemicals, pharmaceuticals, and agrochemical intermediates.
• Surface Cleaning & Etching: Utilized in formulations for electronic circuit board cleaning and metal surface treatment.
• Disinfection & Sanitization: Effective in formulations for hard surface disinfectants, particularly where chlorine-based products are undesirable.

Quality Control

Our Potassium Peroxymonosulfate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for active oxygen content, purity, and stability. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat, sparks, and open flame. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and decomposition. Incompatible with combustible materials, strong acids, reducing agents, and organic compounds. Store separately.
