An insoluble material for adsorbing a pyrogen comprising a polymer of an aziridine compound. According to the present invention, a large amount of the pyrogen can be easily removed from a solution containing pyrogen, and a large amount of the material for adsorbing the pyrogen can be prepared in easy steps. Therefore, the adsorbing material can greatly contribute to the preparation of medicines.

Material for adsorbing pyrogen

An insoluble material for adsorbing a pyrogen comprising a polymer of an aziridine compound. According to the present invention, a large mount of the pyrogen can be easily removed from a solution containing pyrogen, and a large amount of the material for adsporbing the pyrogen can be prepared in easy steps. Therefore, the adsorbing material can greatly contribute to the preparation of medicines.

Method of adsorbing pyrogens

A regenerated cellulose composition having excellent adsorptivity and flame resistance prepared by a process in which viscose, a solvent-adsorbing active carbon in the form of an aqueous dispersion and a specific phosphorus flame retarder are extruded into a coagulation bath to regenerate cellulose which is dried at a temperature not lower than the boiling point of the solvent, whereby the adsorptivity of active carbon is maintained at a high level while a flame resistance is imparted to cellulose.
