| Outline of Final Research Achievements |
In comparison to the conventional particulate-packed columns, monolithic columns possess higher porosity, and able to achieve high reaction and separation efficiency; therefore, they have attracted much attention as a separation, adsorption as well as catalytic supports. In preparing capillary-sized monolithic separation columns, in-situ polymerization method is generally used. As long as the present heating furnace method is used, it takes approximately 5 days to prepare a silica-based monolithic capillary column, and for the case of polymer-based monolithic capillary column, about 1 day is usually needed. In this study, rapid preparation of polymer-based monolithic capillary columns using microwave-assisted polymerization was optimized. The research was focused mainly on the preparation of high ion-exchange capacity monolithic columns, i.e. the amount of time taken during the column pretreatment, polymerization and surface chemical modification processes was shortened dramatically.

| Academic Significance and Societal Importance of the Research Achievements |
マイクロ波を利用した反応は，従来技術に比べて選択的，かつ数十分の一程度のエネルギーで，カラムの調製が可能な特色を有す。従来の加熱法では，モノリス調製の成功率がわずか30％であることに対して，マイクロ波照射を利用した場合，調製されたモノリスの80％が高い分離性能を示す。本研究は，分析システムの小型化によってシステムの消費電力が少なくなり，分析に必要な溶媒も数百分の一程度になるため，廃溶剤による環境負荷を大幅に低減することができる。
