Wood-based activated carbon is an adsorption material with a rich pore structure. Its unique physical and chemical properties make it irreplaceable. Common uses for activated carbon include water purification, air filtration, and medical toxin removal. In the environmental protection, the application of wood-based activated carbon is particularly crucial. Industrial production generates a large amount of wastewater containing toxic, for example chemical wastewater, printing and dyeing wastewater, and so on. Researchers are exploring new uses for activated carbon in energy storage systems like supercapacitors. The pollutants in these wastewaters are complex in composition and high in concentration. If discharged directly, they will cause severe water pollution. Wood-based activated carbon, with its huge specific surface area and developed pore structure, can mostly adsorb heavy metal ions, and so on in wastewater. The treated wastewater can meet discharge standards and even be reused, effectively reducing the pressure of industrial wastewater on the environment. And then, in air purification, wood-based activated carbon also shows excellent performance. It can be used to treat industrial exhaust gases, such as adsorbing formaldehyde, benzene and so on, as well as removing odors and harmful gases in the air. It has important applications in indoor air purification, vehicle exhaust treatment, and industrial exhaust gas control, providing strong support for improving air quality.
In the food and pharmaceutical industries, wood-based activated carbon also plays a important role. In food producing, many food raw materials requires to be decolorized and deodorized to improve product quality and taste. In the sugar industry, the crude sugar liquid obtained from sugarcane or sugar beets contains impurities such as pigments and gums. Wood-based activated carbon can adsorb these impurities, making the sugar liquid clear and transparent, and producing white sugar. In the refining of edible oil, it can remove pigments, odorous substances, and harmful substances from the oil, improving the quality and safety of edible oil. In the pharmaceutical field, wood-based activated carbon is often used for the purification and refinement of drugs. Many drugs produce by-products and impurities during synthesis or extraction, and wood-based activated carbon can selectively adsorb these impurities, improving the purity and efficacy of drugs. Thereby, in some detoxification drugs, wood-based activated carbon also plays an important role. It can adsorb toxins in the body, reduce the absorption of toxins, and achieve the purpose of detoxification.
In the water treatment industry, it is used wide application field, including not only industrial wastewater treatment but also extensive use in drinking water purification. This manual outlines practical uses for activated carbon in chemical processing and waste treatment facilities. With the improvement of people's needs for drinking water quality, traditional water treatment methods are not sufficient. Wood-based activated carbon can remove organic matter, residual chlorine, odors, and so on from drinking water, improving the safety. In some areas, due to geological reasons or pollution, drinking water may contain excessive a lot of iron, manganese, arsenic and so on. Using wood-based activated carbon for deep treatment can reduce the content of these substances, ensuring people's health. And then, in the deep treatment stage of sewage treatment plants, wood-based activated carbon is also used to further remove trace pollutants in water, enabling the treated water to meet higher water quality standards and achieve the recycling of water resources.
In addition to the above main fields, wood-based activated carbon also has wide applications in other industries. In the chemical industry, it can be used as a catalyst carrier to improve the activity and stability. In friendly batteries, it can be used as electrode material to improve battery performance. In the agriculture, wood-based activated carbon can improve soil structure, enhance soil water and nutrient retention capacity, and so on. In the military, it can be used to make gas masks to adsorb toxic gases and chemicals, protecting soldiers' health. With the development of science and technology, the application fields of wood-based activated carbon are still expanding. Its unique adsorption performance and environmental protection characteristics make its application prospects in various fields increasingly broad, making significant contributions to human production and life as well as environmental protection.
