Description
Classification: Hydrogen Peroxide
MF: H2O2
Place Of Origin: China
Hazard Class:5.1+8
HS Code:2847000000
UN:2014
As an advanced oxidation technology, it is used to treat industrial wastewater containing refractory organic matter, such as printing and dyeing wastewater, pharmaceutical wastewater, etc. It can produce hydroxyl free radicals with strong oxidizing properties, decompose organic matter in wastewater into harmless substances such as carbon dioxide and water, reduce the chemical oxygen demand (COD) and biological oxygen demand (BOD) of wastewater, improve the biodegradability of wastewater, and make it easier to be treated by subsequent biological treatment processes.

Packaging
Usually, materials such as high-density polyethylene (HDPE) and polypropylene (PP) are selected. These plastics have good chemical stability, are not easy to react with hydrogen peroxide, can effectively prevent the decomposition of hydrogen peroxide, and have certain flexibility and impact resistance, which can prevent the container from breaking due to collision and other reasons.
Storage environment
1. Temperature: Hydrogen peroxide should be stored in a cool, ventilated warehouse, and the temperature should not exceed 30℃. Too high temperature will accelerate the decomposition of hydrogen peroxide, reduce its effective ingredient content, and may increase the accumulation of oxygen produced by decomposition, posing safety risks.
2. Humidity: Relative humidity should be kept below 80%. Too high humidity may cause hydrogen peroxide to absorb moisture in the air, dilute its concentration, and in some cases may promote decomposition reactions caused by impurities.
3. Light: Hydrogen peroxide is sensitive to light, and light will cause it to decompose, so it should be stored in a light-proof place. Brown glass bottles or opaque materials (such as black plastic covers) can be used to shade the storage container.

FAQ
Q: What does hydrogen peroxide do?
A: Hydrogen peroxide, the common name for hydrogen peroxide aqueous solution (colorless, odorless, transparent), is widely used as a strong oxidant and disinfectant in sterilization, sewage treatment, dyeing and weaving, bleaching and other fields; the concentration used is usually between 3% and 30% (mass fraction), and it can quickly decompose and produce oxygen at lower concentrations; among them, the commonly used concentration for medical disinfection is 3% to 5%, and the higher the concentration, the stronger the oxidizing property.
Q: Is hydrogen peroxide a bleaching agent?
A: Hydrogen peroxide Hydrogen peroxide (hydrogen peroxide) is not only a standing medicine in the first aid kit or a bleaching agent for hair highlights, but also can bleach clothes and remove stains. It is relatively mild and does not harm the environment. When hydrogen peroxide is exposed to the sun, it naturally decomposes into water and oxygen, and is a biodegradable oxygen-based bleaching agent.
Q: Can hydrogen peroxide kill mold?
A: Hydrogen peroxide is another effective way to kill mold.
Q: Is hydrogen peroxide flammable?
A: Not flammable. The substance may ignite flammable materials. Risk of fire and explosion on contact with heat or metal catalysts.
