- Laboratory use: As an oxidising agent in analytical chemistry and preparation of peroxy compounds
- Environmental applications: Treatment of contaminated soil and groundwater (chemical oxidation)
- Food industry: Cleaning and sterilisation (only under approved guidelines and lower concentrations)
Benefits:
- Provides powerful and effective oxidation for industrial processes
- Leaves no toxic residues, decomposing into harmless by-products
- Versatile application in diverse industries
- Ensures consistent and reliable results due to its high concentration
How to Use:
- Use as per specific industrial or laboratory protocols and standard operating procedures (SOPs).
- Dilute carefully if lower concentrations are required for application.
Safety Precautions:
- Corrosive and strong oxidiser; causes severe skin burns, eye damage, and respiratory irritation.
- Reacts violently with organic materials, reducing agents, and combustibles.
- Use personal protective equipment (PPE) including gloves, goggles, face shield, and protective clothing.
- Ensure use in well-ventilated areas and avoid contact with flammable materials.
- Store in tightly sealed containers in a cool, dry, well-ventilated area, away from heat, direct sunlight, and incompatible substances.
