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.
