Abstract
In an adsorbent of the present invention, at least a surface and its vicinity thereof is composed of an apatite represented by the formula Ca10(PO4)6((OH)1-xAx)2, where A represents a halogen element and 0≦x≦1, and a phosphate group contained in the apatite is bonded to a trivalent metal ion. Further, preferably, the trivalent metal ion is Fe3+. According to the present invention, it is possible to provide an adsorbent capable of specifically adsorbing an object compound, an adsorption apparatus capable of separating and purifying the object compound easily and reliably, and a method capable of manufacturing such an adsorption apparatus easily in a short time.
Claims16
An adsorbent having a surface, comprising an apatite which forms at least the surface and its vicinity of the adsorbent and is represented by the formula Ca10(PO4)6((OH)1-xAx)2, where A represents a halogen element and 0≦x≦1, and a trivalent metal ion bonded to a phosphate group contained in the apatite.
A method for manufacturing an adsorption apparatus, wherein a solution containing a trivalent metal ion is passed through an adsorbent filling space of a column filled with an apatite represented by the formula Ca10(PO4)6((OH)1-xAx)2, where A represents a halogen element and 0≦x≦1, so that a phosphate group contained in the apatite is bonded to the trivalent metal ion.
