Abstract: A phosphorus adsorbent, which is used for adsorbing phosphorus in extracorporeal circulation, is a powder comprising a carbonate of a rare earth metal or an oxide of a Group 4 element and having a solubility in 100 g of water at 20° C. of 10 mg or less. The porous fiber, which comprises the phosphorus adsorbent carried therein, shows a change in pH value of from −1.0 to +1.0 inclusive before and after stirring in physiological saline for 4 hours. The phosphorus adsorption columns respectively comprise the phosphorus adsorbent and the porous fiber each disposed therein.

Abstract: The present invention provides efficient reaction conditions by clarifying a relationship between a contact time and an optimum particle diameter etc. in a method for reacting a reaction object with a liquid containing the reaction object being in contact with a granular porous body. The upper limit D (mm) of the particle diameter of the granular porous body is determined from D=0.556×LN (T)+0.166 in a column flow method in non-circulation type, and determined from D=0.0315×T+0.470 in the column flow method in a circulation type and a shaking method. The contact time T (seconds) is given by a value obtained by dividing the volume (m3) of the granular porous body by the flow rate (m3/second) of the liquid in the column flow method in non-circulation type, given by a value obtained by multiplying the fluid flow time (seconds) of the liquid by a volume ratio obtained by dividing the volume of the granular porous body by the volume of the liquid in the column flow method in a circulation type, and given by a value obtained by multiplying the volume ratio by the elapsed time (seconds) after addition of the granular porous body in the liquid in the shaking method.
