PURPOSE: To selectively adsorb and separate phosphopolyol by bringing a phosphopolyol-containing solution into contact with the porous adsorbent having an aliphatic amine type functional chain whose chain strength is 2-50 and a pore size of 1nm-20μm bonded to a base material.
CONSTITUTION: A porous adsorbent is prepared by bonding an aliphatic amine type functional chain whose chain length is 2-50 to a porous base material composed of a polyhydroxyl polymer and having a pore size of 1nm-20μm. A solution containing a phosphopolyol compound is brought into contact with the porous adsorbent to selectively adsorb and hold the phosphopolyol compound from the solution to separate the same. As the porous adsorbent, one to which a primary or secondary amine type aliphatic functional chain is bonded is pref. A drug solution wherein the phosphopolyol compound is a pyrogen and ion intensity is μ=0.03-0.5 can be pref. adapted.
