Research Abstract |
A novel adsorbent was developed by immobilizing a temperature-responsive polymer (the volume of this polymer changes with changing in the solution temperature) on the external surface of adsorbent. This material adsorbed and desorbed molecules with pH of the solution reversibly at lower temperature of 25℃, while it did not adsorb and desorb molecules independent of pH of the solution at higher temperature of 40℃. Also, it was found this phase-transition temperature shifted by about 5℃ to the higher temperature for the adsorbent prepared by the addition of cross-linking agent during the polymer synthesis. From these results, this temperature-responsive adsorbent can be applied to the carrier for drug delivery system and column packing agent for temperature-gradient chromatography.
