Ion exchange resin for pharmaceutical refining and purification The purification and purification of the drug is to convert the active ingredient in the drug solution into an ionic form, ion exchange with the resin, adsorb the active ingredient, convert the active ingredient into a salt by the principle of acid-base salt formation, and then elute the drug. The low concentration of the active ingredient in the extract is eluted on the adsorption column, and the content of the active ingredient is increased to achieve the purpose of purification and purification. The application of the antibiotic is also applied in other drugs. Suzhou Bojie Resin provides pharmaceutical refining and purification resin with high exchange capacity, good mechanical strength and convenient regeneration. It can effectively extract the active ingredients in the drug and improve the performance of the drug.
