摘要

A process for recovering ceftazidime from an aqueous solution containing it, said solution being at a pH in the range 2.0 to 5.5, which comprises contacting the said solution with a non-functional macroreticular resin suitable for adsorbing ceftazidime, eluting the ceftazidime and isolating it, if desired in the form of a salt or hydrate.
