Ion exchange is a very effective compound separation and purification technology that involves ion exchange resins' selective adsorption and release properties to achieve the separation of ions in solution. Owing to its 'green' status, CD BioSciences-GreenChemistry applies ion-exchange separation and purification compounds to clients from the industries of water treatment, pharmaceuticals, food, and chemicals. Alongside this branch, we have developed methods that are ecologically sustainable, efficient, and personalized according to the requirements of the clients.
Ion exchange technology is an important chemical separation and purification method widely used in various fields, especially in the separation and purification of compounds. The technology achieves selective adsorption and separation of specific ions in the solution by the adsorption and releasing functions to allow purification, analysis, and concentration of samples.
Owing to ion exchange being a physical separation process, it does not require the injection of chemical reagents and there is no negative impact on the environment. Furthermore, by choosing the right ion exchange materials and improving the operating conditions, cost-effective recovery and separation of metal ions can be realized, which assists in resource utilization and reduction of pollution to the environment.

CD BioSciences-GreenChemistry, as a company that has the best green chemistry technology, has pledged to deliver separation and purification of compounds via ion exchange technology at very high standards. Our entire service and every technical detail is carefully designed and under strict quality control.
Selection of Ion Exchange Resin
According to the physical and chemical properties of the target compounds, we carefully select suitable ion exchange resins. For example, we offer anion exchange resins for the separation of acidic compounds such as carboxylic acids, sulfonic acids, and phosphates, and cation exchange resins for the separation of basic compounds such as amines.
Separation and Purification of Compounds
We perform ion-exchange separation and purification operations under strict operating conditions. By precisely controlling the flow rate, temperature, pressure, and other parameters of the solution, we ensure adequate contact and exchange between the resin and the target compounds.
Post-treatment and Quality Control
After completing the separation and purification of the target compounds, we carry out the necessary post-processing of the resulting products, such as washing, drying, concentration, etc., to improve the purity and stability of the products.

The active groups are acidic, and the common ones are strong acidic groups, such as sulfonic acid group (-SO3H-SO3Na); weak acidic groups, such as carboxyl group (-COOH) and phenol group (-OH); and medium acidic groups, such as phosphoric acid group (-PO3H2) and so on.
The active group is the alkaline group, and the common ones are: strong alkaline groups, such as quaternary ammonium group -N(CH3)3+X- group, whose scarf X- is OH-, NO3-, etc.; weakly alkaline group, such as primary amine group -NH2, secondary amine group =NH, and tertiary amine group =N.
The active group is the stinging function group, such as the sulfhydryl type chelating resin is the sulfhydryl group attached to the natural fiber macromolecule or resin skeleton and produced, chelating ion exchange resin has good selective adsorption ability.
CD BioSciences-GreenChemistry provides ion exchange-based compound separation and purification services, which have demonstrated excellent performance in many fields due to their high efficiency, precise separation capability, and green advantages.
