High purity tannic acid preparation resin

Tannic acid belongs to a kind of natural plant polyphenol. The industrial tannic acid has a mass fraction of about 80%. It also contains impurities such as gum, pigment, glucose, gallic acid and inorganic salts. It cannot meet the requirements of consumption and must be purified.

The macroporous adsorption resin has good chemical stability, is insoluble in water and organic solvents, is not contaminated, has good mechanical properties, and has low fluid resistance. The resin adsorption separation method has the advantages of simple operation, high selectivity, and reusable use.

Suzhou Bojie Resin Technology Co., Ltd., own brand Bestion. The macroporous adsorption resin which is specialized in separating and purifying tannic acid has the advantages of good selectivity, large adsorption capacity, high mechanical strength, convenient regeneration treatment, fast adsorption speed and easy desorption, and is widely praised by customers.
