Adsorption and recovery of rifamycin B and rifamycin S using basic ion exchange resins

摘要

The use of basic ion exchange resins to adsorb rifamycin B or rifamycin S from dilute solutions containing rifamycin B or rifamycin S is disclosed. The rifamycin B or rifamycin S may be recovered from the resin by desorption with a suitable desorbing solvent system.
