Coconut shell activated carbon is made from high-quality coconut shells and processed through a series of production processes. Coconut shell activated carbon has a black and granular appearance, with developed pores, good adsorption performance, high strength, easy regeneration, and economic durability. However, due to issues such as the origin of coconut shell, its price is higher than that of conventional wooden activated carbon.

The product is widely used in daily life, industry, liquid-phase adsorption, water purification, and gas-phase adsorption. Especially suitable for industries such as power plants, petrochemicals, refineries, printing and dyeing textile industry, food and beverage, pharmaceutical water, electronic high-purity water, domestic drinking water, industrial water reuse, etc. It can effectively adsorb free chlorine, phenols, sulfur, oil, gum, pesticide residues and other organic pollutants in water, residual chlorine, semi dechlorination value, and the recovery of organic solvents.
The adsorption effect of coconut shell activated carbon is mainly based on its unique pore structure and surface chemical properties.
Physical adsorption: Its abundant micropores, mesopores, and macropores provide a large number of adsorption surfaces. When gas or liquid molecules approach the surface of activated carbon, they will be adsorbed on the pore surface due to van der Waals forces between molecules. Pores of different sizes have selective adsorption effects on substances of different molecular sizes. Micropores mainly adsorb small molecule substances, while mesopores and macropores facilitate the diffusion and adsorption of large molecule substances.
Chemical adsorption: There are some functional groups on the surface of activated carbon, such as hydroxyl and carboxyl groups, which can react chemically with certain specific substances to form chemical bonds, thereby adsorbing the substances on the surface. For example, chemical adsorption can enhance the adsorption effect of activated carbon on polar molecules or substances with specific chemical properties.

1. High adsorption performance: Due to its large specific surface area and developed pore structure, coconut shell activated carbon has strong adsorption capacity for various organic pollutants, odors, pigments, heavy metal ions, etc. It can quickly and effectively remove harmful substances from water and air, achieving the goal of purification.
2. Good physical and chemical stability: It has high mechanical strength, is not easy to break and pulverize, and can maintain stable performance under different environmental conditions (such as different acidity and alkalinity, temperature, etc.). It is not easy to undergo chemical reactions and deteriorate, and can play a long-term stable adsorption role.
3. Regeneration: Coconut shell activated carbon saturated with adsorption can be regenerated through various methods, such as thermal regeneration, chemical regeneration, etc. The adsorption performance of regenerated activated carbon can be well restored and reused, reducing the cost of use and minimizing waste emissions to the environment.
4. High safety: Coconut shell activated carbon itself is non-toxic and odorless, and will not cause harm to human health and the environment. During use, it will not release harmful substances and is a safe and reliable environmentally friendly material.
5. Wide application range: It can be widely used in various fields such as water treatment, air purification, food and beverage processing, chemical industry, pharmaceuticals, gold extraction, etc. It has good removal effects on different types of pollutants and meets various purification needs.
