| Outline of Final Research Achievements |
Adsorption behavior of drugs (ibuprofen and ketoprofen) onto MCM-41-type mesoporous silica using supercritical carbon dioxide was studied for preparation of nano DDS (drug delivery system) career. The experiments were carried out at temperatures from 313 to 343 K and at a pressure of 15.0 MPa. The loading amount of the drugs onto the mesoporous silica adsorbent increased with increasing temperature. This can be attributable to the solubility of the drug in supercritical carbon dioxide and competitive adsorption of carbon dioxide with the drug. Therefore, efficient design of the preparation process of the supercritical carbon dioxide method requires considerations of these effects for the drug loading onto the mesoporous material.
