325 Mesh Wood Based Powder Activated Carbon for Fine Chemical Liquid Purification
Product Introduction
Wood-based powdered activated carbon is designed for the purification, clarification, and decolorization of fine chemical liquids such as intermediates, organic acids, solvents, and specialty additives.
It efficiently removes colored compounds, trace metals, and organic residues generated during synthesis or oxidation reactions, improving product color, stability, and purity.
Produced from premium hardwood feedstock and activated under strictly controlled conditions, this 325 mesh fine-grade carbon features an optimized pore structure and high surface area, making it ideal for high-value fine chemical refining processes that demand precise adsorption control and excellent filtration performance.
