Acid-etched coal-based activated carbon
Acid-washed coal-based activated carbon is produced using high-quality anthracite as raw material. After undergoing conventional activation and shaping, it undergoes deep acid washing purification and high-temperature drying processes to achieve refinement. Its core advantage lies in the acid washing process, which effectively removes residual metal oxides, heavy metal ions, and water-soluble inorganic salt impurities from the raw material, significantly enhancing product purity and surface cleanliness. This product retains a well-developed porous structure while keeping the content of metal impurities such as iron, aluminum, calcium, and magnesium under control, preventing secondary pollution. It is particularly suitable for applications sensitive to residual metal ions, including high-purity water treatment, electronic-grade ultra-pure water production, deep decolorization of food and beverages, and purification of precision chemical waste liquids.
