Application: The application range of activated carbon is very wide. Its application almost involves various fields of the national economy. In gas se adsorption, it is used to remove harmful gases from exhaust gas, air purification in environmental protection, solvent recovery, flue gas desulfurization, atomic radiation. Protection and removal of nuclear fission radioactive materials and radioactive iodine, krypton, xenon, etc. that escaped from the atomic energy facility. In liquid se adsorption, it is used in the purification and purification of glucose, caramel, sugar, dairy products, edible oil, fruit juice drinks, alcoholic beverages, food additives such as monosodium glutamate, citric acid, agar, pectin and other foods in the food industry; Purification and purification of various medicines and injections in the rmaceutical industry; purification, purification and recovery of various chemical drugs and industrial oils in the chemical industry; wastewater treatment, water treatment; synthetic fiber industry, petroleum refining, etc., and used as catalysts And catalyst carrier. With the development of science and technology, the variety and adsorption capacity of activated carbon will be further increased and improved. For example, recently developed and researched activated carbon with high specific surface area, its surface area can reach 3000m2/g, and the application range of activated carbon will be wider.
