Activated carbon, derived from coconut shell in 16-32 mesh size with pH 9-10, is a highly porous form of carbon used extensively in chemical processes, including the production of trimeric hydrogen chloride for adsorption and purification. It is widely applied in water purification and air filtration systems to remove contaminants and impurities. In various industries, it serves as a catalyst support, decolorizing agent in food and pharmaceutical processing, and adsorbent in gas separation and solvent recovery. Its versatile adsorptive properties make it essential in environmental remediation, gold recovery in mining, and as a filtering medium in respirators and protective equipment.
