| Research Abstract |
The adsorption and desorption behaviors of Pt nanoparticles in water for the temperature-responsive adsorbent have been investigated by the temperature-swing operation. As the temperature-responsive adsorbent, the copolymer gel composed of N-isopropylacrylamide (NIPA) and vinylbenzyl trimethylammonium chloride (VBTA) was employed. As a result, it was found that the NIPA-VBTA gel can adsorb Pt nanoparticles at 333 K and desorb some of pre-adsorbed nanoparticles at 298 K repeatedly by the temperature-swing operation.
