COLUMN HAVING FUNCTION FOR SEPARATING METAL, AND METHOD FOR SEPARATING AND RECOVERING METAL

摘要

PROBLEM TO BE SOLVED: To dissolve the problem that it is not sufficient in adsorptivity, processability of granulation, labor and facility for attachment/detachment, cost for regenerating an absorbent and productivity of recovery in the conventional absorbent.

SOLUTION: This column has a function for separating a metal and is provided with one or more kinds of functional material groups disposed in a flowing passage range in contact with metal ion mixing solution in the column, at least one or more of pouring holes for pouring the mixing solution into this range in the column and at least one or more of discharge holes for discharging the mixing solution from this range in the column. Then, the functional material is constituted of an organic material and further, this material has an inner hollow part and the metal is separated from the solution by including the metal to be removed into this inner hollow part or forming the complex material with the metal.
