Powdered activated carbon is a black powdery adsorbent material, which is made from high-quality carbon-containing raw materials such as wood, coconut shells, and coal through a series of fine processing techniques including carbonization and activation. Due to its extremely fine powder state, it has a large specific surface area and abundant pore structure, enabling it to quickly and effectively adsorb impurities, pigments, odors, and harmful substances in various gases and liquids. It is a widely used adsorbent.
