| 英文摘要 | A novel radioactive pollutants remover was rationally designed and synthesized in this study. It was found that the high ratio of Ti/Si was essential to get a silicotitanate with an open 8-membered ring pore framework. Sol-gel hydrothermal synthesis was adopted to prepare high quality products. Hydrolyzation of titanium and silicon containing materials were balanced to promote the place-holding of titanium element in the framework. Chemical analysis shows that molecular formula of the product is Na4Ti4Si3O10 center dot 4.5H(2)O and the ratio of Ti/Si of the product synthesized is about 1.33, which is much higher than the molecular sieves commonly used, such as TS1, TS2 and MCM41. Raman spectrum analysis shows that all of the Ti atoms act as the framework elements to form an open 8-membered ring pore structure. Na4Ti4Si3O10 center dot 4.5H(2)O shows a quite high Cs+ removing ability even in a lower. pH solution. And the sequence of distribution coefficient with metal ions is K-dCs >> K-dk > K-dZr > K-dCa > K-dMg > K-dC. So it can be used as a promising new Cs+ element removal in both acidic and basic radioactive wastewater. |
