CARBONACEOUS ADSORBENT FOR REMOVAL OF PYROGEN AND METHOD OF PURE WATER USING SAME

摘要

A carbonaceous adsorbent to be used for the removal of a pyrogen dissolved in water is disclosed. The adsrobent is obtained by carbonizing porous beads of a cross-linked polymer. This adsorbent is favorably used for the removal of endotoxin in the production of pure water from deionized water resulting from the treatment with ion-exchange resins.
