A comparative study is performed to compare the defluorination performance of five sorbents with alumina and modified alumina prepared by c-precipitation methods. The activated composite oxides of Zr-Al and Mg-Y-Al derived from hydrotalcites of Mg-Y-Al and Zr-Al showed that the removal rate of fluoride were appropriately 98.8% and 98.0% respectively, and their defluorination were affected slightly by the influencing factors of adsorption.
