Hydrogen peroxide (hydrogen peroxide, chemical formula H2O2) is an important inorganic chemical product and an important oxidant, bleach, disinfectant and dechlorinating agent in the industrial field. It is widely used in textile, papermaking, chemical industry, light industry, medicine, electronics, food, environmental protection and other fields. At present, China's hydrogen peroxide products are divided into industrial grade, reagent grade, pharmaceutical grade and electronic grade, with concentrations of 27.5%, 35%, 50% .70% and other specifications.
Main application areas of hydrogen peroxide
1. Textile Industry
Hydrogen peroxide in the textile industry is mainly used for fabric bleaching, color development when vat dyes are dyed, and fabric desizing, such as the bleaching of high-grade pure cotton fabrics, linen-free fabrics, knitwear and towels, bed sheets, fur, and crafts.
2. Chemical Industry
In the chemical industry, hydrogen peroxide is widely used to prepare epoxy compounds, organic peroxides and inorganic peroxyacids and their salts, to oxidize organic nitrogen-containing, organic and inorganic sulfur-containing compounds, but also to catalyze polymerization reactions and so on.
3. Paper Industry
Hydrogen peroxide used in the paper industry can be divided into pulp bleaching and waste paper deinking treatment. When used for pulp bleaching, it is mainly used for the bleaching of mechanical pulp (milled wood pulp); when used for the treatment of waste paper, it can separate the ink particles from the paper fibers, and finally make the recovered pulp obtain a satisfactory whiteness. This is hydrogen peroxide in the future The most promising application field in the flower and paper industry.
4. Food Industry
Generally, food-grade hydrogen peroxide is used, and the concentration of the mother liquor is mostly about 30% to 50%. When used, it is diluted to an appropriate ratio as needed. Food grade hydrogen peroxide can be widely used in the production process of dairy products, beverages, purified water, mineral water, aquatic products, fruits, vegetables, poultry and meat products, pickled products, beer and other foods. Used for disinfection, sterilization, bleaching, etc.
V. Environmental governance
Hydrogen peroxide not only does not produce pollutants when used, but can also be directly used to effectively treat industrial waste, especially wastewater treatment, and can treat almost all kinds of toxic wastewater (including detoxification, deodorization, decolorization) without secondary pollution. Hydrogen peroxide can be used to remove NO, sulfur trioxide, mercaptans, aldehydes, etc. from exhaust gas, and can also be used to treat sulfur or sulfide, phenol, and cyanide-containing wastewater. Hydrogen peroxide can also be used to eliminate groundwater and soil pollution by organic matter .
6. Electronics Industry
In the electronics industry, hydrogen peroxide and other chemicals can be used to make corrosive fluids and cleaning agents. In addition, many electroplating processes in instrumentation, electromechanical, daily driving parts and other industries use hydrogen peroxide to treat the plating solution.
Seven, medical hydrogen peroxide
Hydrogen peroxide has an oxidizing effect, but the concentration of medical hydrogen peroxide is equal to or lower than 3%,
Medically, 3% hydrogen peroxide is commonly used to disinfect wounds or otitis media.
3% hydrogen peroxide has the ability to disinfect and sterilize. In addition, 2% to 3% hydrogen peroxide is often used as a flushing medicine in stomatology. Therefore, due to its oxygen-generating effect, hydrogen peroxide is widely used in oral clinical medicine.
8. Disinfection
Hydrogen peroxide is a colorless liquid with a pungent odor. Medically, 3% hydrogen peroxide is commonly used to disinfect wounds or otitis media.
9. Beauty
Hydrogen peroxide
Hydrogen peroxide is not only a medical product, but also has the function of lightening hair color.
Rapid detection method of hydrogen peroxide concentration
Hydrogen peroxide (hydrogen peroxide) is an important oxidant, bleach, disinfectant and dechlorinating agent. And can be provided in rocket fuel, organic or inorganic peroxides, foam plastics and other porous materials. It can also be used for the bleaching of cotton fabrics and other fabrics; the bleaching and deinking of pulp; the manufacture of organic and inorganic peroxides; organic synthesis and polymer synthesis; the treatment of toxic wastewater.
Fast detection method of hydrogen peroxide
At present, the analysis methods of hydrogen peroxide include high-performance liquid chromatography, spectrophotometry, and chemical titration, of which chemical titration is the mainstream detection method, and includes potassium permanganate titration and iodometric method. These detection methods all have the disadvantages of requiring detection reagents, complicated detection methods, complicated manual operations, serious chemical pollution, and low detection speed, which are not conducive to rapid reading of results. Refractive index method is now used to detect the concentration of hydrogen peroxide solution is a fast and simple method, and the operation is convenient, without the need for chemical reagents. The current measuring instruments include: concentration meters, digital display concentration meters, hand-held concentration meters, hydrogen peroxide concentration meters and other measurement tools.
ATAGO's new PAL-39S hydrogen peroxide concentration meter, a rapid measuring instrument, hydrogen peroxide refractometer, uses the principle of refraction to quickly and easily detect the concentration of hydrogen peroxide. Only about 0.5ml of sample is needed, and the measurement results are displayed 3 seconds after dropping. , Easy to operate.
The PR-50HO hydrogen peroxide concentration tester and hydrogen peroxide refractometer have higher accuracy and service life, and can quickly and easily detect the hydrogen peroxide concentration. Only about 0.5ml of sample is required, and the measurement results are displayed 3 seconds after dropping. Through the battery design, Hand-held portable, easy to operate, accurate measurement.
