325 Mesh Wood-Based Powdered Activated Carbon for Amino Acid & Vitamin Decolorization with High Decolorization Power and Optimized for Small Molecules
325 Mesh Wood Based Powder Activated Carbon for Amino Acid & Vitamin Decolorization
Product Introduction
Wood-based powdered activated carbon is specially developed for the refining, decolorization, and purification of amino acid and vitamin solutions. It efficiently removes pigments, colloidal substances, fermentation by-products, and trace organic impurities from complex liquid systems, achieving excellent color removal and stability without affecting target molecule yield.
Produced from high-quality hardwood materials through precisely controlled carbonization and activation processes, this fine-grade 325 mesh activated carbon features superior adsorption kinetics and a uniform microporous structure optimized for small-molecule and high-color applications. Its high purity and fine particle size make it ideal for amino acid, vitamin, and pharmaceutical intermediate production.
