Citric acid is an important organic acid, also known as tannic acid, which usually contains one molecule of water of crystallization, is odorless, has a strong acidity, and is easily soluble in water. Anhydrous citric acid can be obtained by controlling a suitable temperature during crystallization. It has many uses in industry, food industry, and cosmetics industry.

The ion exchange resin is used as an adsorbent, and the opposite charge in the solution is adsorbed on the ion exchange resin by electrostatic attraction, and then the adsorbate is eluted from the ion exchange resin with a suitable eluent to achieve separation and purification. .

Suzhou Bojie Resin Technology Co., Ltd. provides citric acid separation and purification resin with high exchange capacity, large adsorption capacity, convenient regeneration and good mechanical strength, which has been well received by domestic and foreign customers.
