Industrial Use of Hydrogen Peroxide Applications
Hydrogen peroxide is widely used in the industrial field and has many important uses.
Pulp and paper industry
In the pulp and paper industry, hydrogen peroxide is a key bleaching agent. It can effectively remove lignin and other colored substances, making pulp white, and hydrogen peroxide is more environmentally friendly than traditional bleaching agents. It works under mild conditions, does not produce a large number of harmful by-products, and helps to produce high-quality, high-whiteness and environmentally friendly paper.
Textile industry
In the textile industry, hydrogen peroxide is used for the bleaching of fabrics. Whether it is natural fibers such as cotton, linen, or chemical fibers, hydrogen peroxide can remove impurities and pigments, and improve the whiteness and color of fabrics. At the same time, it can also be used in pretreatment processes such as desizing and scouring of fabrics to improve the quality of fabrics and lay a good foundation for subsequent processing such as dyeing and printing.
Chemical synthesis
In the field of chemical synthesis, hydrogen peroxide is an important oxidizing agent. The synthesis of many organic compounds relies on their oxidizing properties to achieve specific chemical reactions. For example, it can be used to prepare epoxy compounds to form epoxy groups by oxidizing olefin double bonds, providing key intermediates for the synthesis of many high value-added chemicals. In addition, hydrogen peroxide also plays an indispensable role in the preparation of peroxide, alcohol, aldehyde and other compounds, promoting the development of organic synthetic chemistry.
Environmental Protection Field
Hydrogen peroxide contributes significantly to environmental protection. In wastewater treatment, it can be used to degrade organic pollutants. For wastewater containing refractory organic matter, the advanced oxidation process participated by hydrogen peroxide can generate hydroxyl radical with strong oxidizing property, decompose complex organic matter into simple inorganic matter, reduce the chemical oxygen demand (COD) of wastewater, and achieve discharge standards. In the field of soil remediation, it can be used to treat soil contaminated by organic pollutants, remove harmful substances in soil through oxidation, and restore soil ecological functions.
Electronics Industry
In the electronics industry, hydrogen peroxide is used for the cleaning and etching of semiconductors and circuit boards. It can effectively remove organic and inorganic impurities from the surface, ensuring the performance and reliability of electronic components. In the manufacturing process of silicon wafers, hydrogen peroxide is used in combination with other chemical reagents to precisely control the thickness of the oxide layer on the surface of silicon wafers, meeting the strict requirements of semiconductor devices for the surface characteristics of materials.
To sum up, hydrogen peroxide plays a crucial role in many industrial fields due to its unique oxidation properties. With the development of science and technology, its application prospects will be broader.
