Carbon powder, typically in the form of activated carbon, is widely used as a decolorizing and refining agent in chemical processes. It effectively adsorbs impurities, colors, and organic contaminants from solutions due to its high surface area and porous structure. This black powder (≥100 mesh) is essential in laboratory and industrial applications for purifying liquids, such as in the production of pharmaceuticals, food, and beverages. It also finds use in water treatment and as a catalyst support. High-purity grades with low acid-soluble material (<1%), iron (<0.05%), and heavy metals (<0.003%) ensure minimal contamination in sensitive processes.
