| Research Abstract |
The adsorption and desorption behaviors of bovine serum albumin (BSA) in water for the temperature-responsive adsorbents have been investigated by the temperature-swing operation. As the temperature-responsive adsorbents, the copolymer gels composed of N-isopropylacrylamide (NIPA) and vinylbenzyl trimethylammonium chloride (VBTA) and the poly(NIPA-co-VBTA) grafted silica particles were employed. As a result, it was found that both copolymer adsorbents can adsorb BSA at 298 K and desorb some of pre-adsorbed BSA at 313 K repeatedly by the temperature-swing operation.
