Activated carbon used for decolorization mainly includes wood activated carbon and coal-based activated carbon, which differ in raw materials, production processes and application fields.

Decolorization principle

The decolorization principle of activated carbon is mainly achieved through physical adsorption and chemical adsorption. Physical adsorption relies on the multi-level pore structure of activated carbon (micropores, mesopores and macropores), which provide a large number of adsorption sites to remove pigment molecules through van der Waals forces and intermolecular attraction. Chemical adsorption further enhances the decolorization effect by chemically reacting or forming hydrogen bonds with pigment molecules through the functional groups on the surface of activated carbon.

Application fields

Activated carbon is widely used in the decolorization, refining, deodorization and impurity removal of products such as food industry, pharmaceutical intermediates, vitamins, antibiotics, etc. For example, it is widely used in sugars, glutamic acid and salts, lactic acid and salts, citric acid and salts, wine, condiments, animal and plant proteins, biochemical products, etc.
