摘要：
The present invention relates to a method for concentrating a dilute aqueous solution of a β-lactam antibiotic which is readily susceptible to heat, by subjecting a dilute aqueous solution of a β-lactam antibiotic, said solution containing 2 to 20% (v/v) of a lower alcohol, to concentration by means of a permeable membrane made of poly-(ether/amide) or polybenzimidazolone.
