Abstract:
1. A method for manufacturing an adsorption apparatus, the adsorption apparatus comprising a column having an adsorbent filling space, and an adsorbent filled into the adsorbent filling space of the column, wherein the adsorbent comprises a plurality of apatite particles, each having a surface, and each comprising an apatite represented by the formula Ca 10 (PO 4 ) 6 ((OH) 1-x A x ) 2 , where A represents a halogen element and 0.3≦x≦1, and Fe 3 ′ bonded to a phosphate group contained in the apatite forming the surface of each of the apatite particles, and wherein average particle size of the apatite particles is in the range of 0.5 to 100 μm and the amount of the Fe 3+ to be bonded to the apatite forming the surface of each of the apatite particles is in the range of 0.1 to 100 mg per gram of the apatite, the method comprising: preparing the column in which the adsorbent filling space is filled with said apatite particles; and passing a solution containing Fe
