| 摘要 |
<p>A photoresponsive copper ion adsorbent material containing a copolymer which is obtained by copolymerization of a monomer component containing both a photoresponsive compound exhibiting reversible metal ion adsorption-desorption transition in dependence of light in a metal ion solution and a quaternized amine compound, wherein the copolymer can selectively adsorb copper(II) ions in a dark place from a metal ion solution containing chloride ions, sodium ions, and copper(II) ions. Thus, only copper(II) ions can be adsorbed selectively among metal ions, and recovered through desorption.</p> |
