研究了以5A分子筛为骨架吸附材料，经在含Al3+或Fe3+溶液中离子交换改性处理，获得了一种可吸附除氟的改性分子筛。实验表明，该种分子筛对水溶液中的低含量氟有良好的吸附性能。静态饱和吸附容量可达28.98和21.4mgF-/g分子筛(分别对含Al3+或Fe3+分子筛)。含氟水经分子筛柱处理后，除氟率可达99%。吸附氟后的分子筛可用柠檬酸盐洗脱氟，洗脱率接近完全。洗脱后的分子筛可重复使用。得到了一种新的效果显著的除氟方法。

Zeolite 5A was modified through ion exchanging in solution ofAl3+ or Fe3+, and got a new material of separating fluor from water including fluoride. The test result shows that this modified zeolite has favourable adsorbing capacity for flour from water. The static saturation adsorbing capacity is 28.98 and 21.4mgF-/g zeolite for the zeolites contain Al3+ or Fe3+ respectively. The 99% of fluor was removed from water including fluoride through treatment of the zeolite column. The fluor adsorbed can be quantitatively eluted with citrate solution. A new remarkable method of remove fluor was got.
