摘　　要：用溶胶 凝胶的方法制备了水合二氧化钛 水合五氧化二锑 (HTO HAP)球形复合无机离子交换剂 ,研究了其对Sr2 +和Cs+的离子交换性能 ,并对其组成、结构及稳定性作了初步的研究 .结果表明 ,此种球形交换剂机械强度好 ,适合装柱 ,在弱酸性条件下对Sr2Spherical 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.
