PROBLEM TO BE SOLVED: To provide a metal adsorbent capable of adsorbing useful and harmful metals dissolved in hot spring water, and to provide a method for recovering and removing useful and harmful metals dissolved in hot spring water by the adsorbent. To do. A method for recovering and removing useful and harmful metals dissolved in hot spring water, comprising a polymer base material and a monomer mainly having a vinyl group introduced into the polymer base material by graft polymerization A hot spring water is passed through a metal adsorbent having a graft chain to be formed and a chelate-forming group introduced into the graft chain. The chelate-forming group is preferably an amidoxime group, a phosphate group, an amine group, an iminodiacetic acid group, or a functional group obtained by supporting zirconium or iron on a phosphate group.
