Outline of Final Research Achievements

Cycrodextrins (CyDs) trous-shaped cyclic oligomer composing of 1,4-linked D-glucopyranose. A variety of organic compounds can be included in their center
cavities in aqueous media. A couple years ago, we have reported hybrid polymer consisted of be-ta-CyD and diatomite. In that report, it was shown that the hyblid polymer was high affinity for Cesium ion. In this study, we prepared hybrid polymers consisted of be-ta-CyD and diatomite, where ratio by weight of be-ta-CyD and diatomite in a reaction mixture was changed ranging from 1:0.5, 1:1, and 1:2. It was shown that the cecium extraction value of those hybrid polymers were over 90 % from 1 min of mixture time and mild acidity-nutral of pH condition.
