Abstract
A method for reacting a reaction object with a liquid containing the reaction object 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 granular porous body includes a skeleton body including an inorganic compound having a three-dimensional continuous network structure, and has a two-step hierarchical porous structure including through-holes formed in voids in the skeleton body and pores extending from a surface to an inside of the skeleton body and dispersed on the surface. A functional group having affinity with the metal ion is chemically modified on a surface of the granular porous body.
