Title:
ADSORPTION METHOD, SEPARATION METHOD, DESORPTION METHOD AND RECOVERY METHOD OF METAL IONS, AND ADSORBENT AND RECOVERY AGENT USED FOR THESE
Document Type and Number:
Japanese Patent JP2015147948
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for collecting metal ions rapidly without using an organic solvent, which enables environmental loads to be reduced, processes to be simplified, and selectivity for metal ions recovered to be improved.SOLUTION: Metal ions are recovered by steps of: making metal ions to be adsorbed by metal powder by contacting the metal powder having calcium phosphate on the surface with a solution containing the metal ions; separating the metal powder having adsorbed the metal ions by magnetic force; and subsequently desorbing the metal ions by eluting the metal ions from the metal powder by reacting the separated metal powder with an extraction agent.
