| Abstract: | Spherical composite inorganic ion-exchangers,hydrated titanium dioxide-hydrated antimony pentoxide(HTO-HAP),were prepared using sol-gel method and their ion exchange properties for Sr 2 and Cs as well as their composition,structure and stability were investigated in this paper.The results show that the micro-sphere has high ion exchange capacity for Sr 2 and Cs in week acid and good mechanical strength for column use. |
