Procedure

In 10 ml. of distilled water is dissolved 1.0 g. of N-[7-(α-sulfophenylacetamido)ceph-3-em-3-ylmethyl]-pyridinium-4-carboxylate sodium salt and the solution is passed over an ion exchange resin (Amberlite IR-120 of Rohm and Haas Co., U.S.A.) to obtain an aqueous solution of free acid N-[7-(α-sulfophenylacetamido)-ceph-3-em-3-ylmethyl]pyridinium-4-carboxylate.
