Active Carbon: Properties, Preparation and Applications
Active carbon, also known as activated charcoal, is a porous carbon material with high specific surface area and excellent adsorption capacity, widely used in various industrial and daily fields. It is typically prepared from carbon-rich raw materials such as coal, wood, coconut shell and fruit pits through carbonization and activation processes, which create a large number of micro-pores and meso-pores in its structure.
The unique porous structure endows active carbon with strong adsorption performance, enabling it to effectively remove impurities, harmful gases, heavy metal ions and organic pollutants. In industry, it is widely used in water treatment, gas purification, catalyst support and solvent recovery. In daily life, it is applied in air purifiers, water filters and deodorants.
With the increasing demand for environmental protection, active carbon plays an increasingly important role in pollution control. Its renewable and recyclable characteristics also make it a green and sustainable material, contributing to the development of eco-friendly technologies.
