Hydrogen Peroxide is a clear, colorless liquid with the molecular formula H₂O₂ and CAS number 7722-84-1. Unlike water (H₂O), the extra oxygen atom makes it a potent oxidizer. Its instability drives it to readily decompose into water and oxygen, a reaction catalyzed by light, heat, and trace metals. This decomposition releases oxygen radicals, which are highly effective at breaking down organic compounds and eliminating pathogens.
In industrial applications, the concentration of Hydrogen Peroxide varies significantly — typically ranging from 3% for food-grade sterilization up to 35% or more for textile bleaching and water treatment. The physical property of slightly higher viscosity than water influences its handling and dosing. Its solubility in water is complete, enabling easy dilution to required concentrations.
The key mechanism behind Hydrogen Peroxide’s efficacy in water treatment involves oxidation of iron, manganese, and organic contaminants, as well as disinfection by producing hydroxyl radicals that disrupt cellular functions in microbes. Unlike chlorine, it does not form harmful chlorinated byproducts, which improves environmental compliance.
Performance is affected by temperature, pH, and contact time. Most water treatment systems dose it continuously or batch-wise to maintain target residual concentrations. It is also used synergistically with catalysts or ultraviolet light in advanced oxidation processes to increase pollutant degradation.
For procurement decisions, purity, grade, and stable concentration are crucial specifications. Confirming these with Zenco Systems Ltd ensures compliance with local regulations and process compatibility. Compatibility with container materials is essential to prevent premature decomposition or container corrosion.
