1. What is fruit-shell activated carbon? Activated carbon is a porous carbon in the form of black powder, particles, or amorphous material. Its main component is carbon, but it also contains small amounts of oxygen, hydrogen, sulfur, nitrogen, and chlorine. It is mainly made from wood, fruit shells, coal, etc., through high-temperature activation. Carbon is the most stable element in nature, and activated carbon shares this property as well. Activated carbon has a large specific surface area (500–1000 m2/g) or a highly porous structure, which confers strong physical adsorption properties; it is capable of adsorbing gases, liquids, or colloidal solids, and the amount of gas and liquid that can be adsorbed can be close to the mass of the activated carbon itself. Its adsorption is selective; non-polar substances are more easily adsorbed than polar substances. Within the same series of substances, the higher the boiling point, the easier it is to be adsorbed. The higher the pressure, the lower the temperature; the higher the concentration, the greater the adsorption capacity. On the contrary, reduced pressure and heating facilitate gas desorption. Activated carbon is commonly used for gas adsorption, separation and purification, solvent recovery, decolorization of sugars, oils, and glycerin, as well as in pharmaceuticals; it is also used to deodorize drinking water, refrigerators, and as a filter in gas masks. Additionally, it can be employed as a catalyst or as a carrier for metal salt catalysts. 2. The function of fruit-shell activated carbon: Activated carbon is also known as activated carbon black. It is black powdery or granular amorphous carbon. Let’s take a look at the function of activated carbon. Activated carbon has strong \"physical adsorption\" and \"chemical adsorption\" capabilities, allowing it to absorb certain organic compounds and thereby achieve removal effects. Activated carbon is now widely used for air purification in cars or indoors. Activated carbon is a porous carbon-containing substance. Its developed pores give it a large surface area, allowing it to come into full contact with toxic and harmful gases in the air. The strong adsorption field around the pores of activated carbon immediately draws toxic gas molecules into the pores, which is why activated carbon possesses a high adsorption capacity. Primary uses: 1. New homes: Used to absorb toxic and harmful gases such as formaldehyde, benzene compounds, ammonia, and radon in the air of new homes, thereby quickly eliminating the unpleasant odors resulting from renovation. New furniture: Used to absorb formaldehyde, benzene compounds, and various odors continuously emitted by new furniture. 3. Wardrobes, bookshelves, shoe cabinets: odor control, detoxification, dehumidification, pest prevention, deodorization, sterilization, and preservation of calligraphy works, etc. 4. Bathroom: Deodorization and sterilization, fresh air. 5. Floor: odor, moisture, mold, moth prevention, and protection against floor deformation. 6. Cars: Absorb various harmful gases from new cars and various unpleasant odors from used cars. 7. Computers, household appliances, etc.: Adsorption to reduce the harm caused by radioactive gases to humans. 8. Offices, hotels, and other public places: Purify the air and eliminate unpleasant odors.
