200 mesh food grade powdered activated carbon is currently the best decolorizing effect obviously. The food-grade powder activated carbon is used to decolorize the solution in the pharmaceutical process and adsorb impurities and small molecular heavy metals in the solution. It is the most commonly used means to remove heat sources. It has the characteristics of sterile, odorless, non-toxic, low impurities, high purity, fast filtration speed, strong adsorption capacity, developed internal pore structure, coarse pores, etc., stable reaction performance, insoluble in common solvents and acids and alkalis, and can be effective Absorb the pigment in the potion, and reduce the impurities in the potion, without affecting the concentration and properties of other ingredients in the potion. Decolorization of vitamin C and other raw materials, decolorization and refining of intermediates, and has the effects of absorbing intestinal bacteria and detoxification. The advantages of powdered activated carbon treatment are: suitable for intermittent processes; easy to control the addition amount; ready-made filtering equipment can be used; and the price is lower.
Activated carbon for medicinal decolorization is widely used in pharmaceutical preparations, pharmaceutical intermediates, food brewing, fine chemicals and other industries. The powder active carbon suitable for the decolorization, purification and purification of antibiotics in the pharmaceutical industry, streptomycin, lindamycin, gentamicin, penicillin, sulfonamides, hormones, amino acids, gallic acid, alkaloids, paracetamol, vitamins and other products. The powder active carbon is also used for the decolorization, refining and removal of “heat sources” of various injection agents. It can also be used to remove impurities, odors, decolorization and refining of electroplating baths, benzotriazole, and chemical raw materials.
