Abstract
An adsorbent includes core particles containing an adsorbing material; a porous coating layer including a polymer material that coats the core particles; and an underlying layer containing a metal compound and disposed between the core particles and the porous coating layer. The porous coating layer is formed by spraying and applying a suspension or a solution containing the polymer material over the adsorbing material, or by immersing the adsorbing material into the suspension or the solution.
