| 摘要 |
A light- and heat-response adsorbent, having an optically responding ability reversibly showing transition to adsorption and release of a soluble substance in a soluble-substance solution in response to whether light is irradiated or not and a thermally responding ability reversibly showing transition to solubilization and precipitation, or swelling and contraction, in response to temperature, preferably containing a copolymer of monomers including 1',3',3'-trimethyl-6-(acryloyloxy)spiro(2H-1-benzopyran-2,2'-indole] and N-isopropylacrylamide. Thus, the invention provides an adsorbent functioning both to adsorb and release a soluble substance from and into solution and having higher soluble-substance recovery efficiency. |
