In our previous study, we found that Ti(OH)(4) exhibited fluoride ion exchange properties. In order to improve the ion exchange capacity, mesoporous Ti oxohydroxide (TiOx(OH)y) had been prepared by using dodecylamine as template. Zirconia and silica had been introduced into the mesoporous Ti oxohydroxide to enhance the ion exchange capacity. The mesoporous structure and the morphology of the mesoporous materials obtained were confirmed using XRD and SEM, respectively. A fluoride ion exchange study was done on each sample. Results showed that mesoporous Ti oxohydroxide containing zirconia exhibited the highest fluoride ion exchange capacity, as it has the smallest particle size, with high uniformity among the mesoporous materials prepared.
在我们之前的研究中，我们发现Ti(OH)(4)表现出氟离子交换特性。为了提高离子交换容量，以十二烷基胺为模板制备了介孔氢氧化钛（TiOx(OH)y）。已将氧化锆和二氧化硅引入介孔氢氧化钛中以增强离子交换容量。分别使用XRD和SEM对所得介孔材料的介孔结构和形态进行了确认。对每个样品进行了氟离子交换研究。结果表明，含氧化锆的介孔氢氧化钛表现出最高的氟离子交换容量，因为它具有最小的粒径，在所制备的介孔材料中具有高度均匀性。
