Application of Powdered Activated Carbon for Decolourisation in Complex Systems
As a highly efficient and economical adsorbent, powdered activated carbon plays an indispensable role in liquid decolourisation processes across numerous industrial sectors. This is due to its enormous specific surface area and highly developed pore structure. From refining pharmaceutical intermediates (e.g., paracetamol, sodium salicylate) and enhancing food industry products (e.g., syrups, fats, beverages), to advanced treatment of chemical and dyeing wastewater (e.g., dyes, organic pigments), its application spans critical stages of product quality control and environmental protection. Its primary advantages lie in relatively low investment costs, rapid reaction speeds, and flexible application. It can swiftly remove colour molecules, turbidity, and other organic impurities from liquids, thereby improving product appearance, enhancing purity, or ensuring wastewater meets discharge standards.
