摘  要:
采用静态吸附法研究了改性高铝水泥对含氟水的除氟性能,结果表明:用硫酸铝溶液0.5 mol/L浸泡高铝水泥8h制成改性高铝水泥,然后用其与含氟水震荡反应7 h,控制含氟水的pH在6~8范围内,能提高改性高铝水泥的吸附率,对含氟10 mg/g的溶液,此优化条件下的最大除氟率约96%。

摘  要:
The removal of aqueous fluoride by adsorption of modified high alumina cement was studied by static adsorption method.The results showed that modified high alumina cement should be made by soaking high alumina cement with 0.5 mol/L Al2(SO4)3 for 8 hours;the optimum conditions for removal of aqueous fluoride were as follows: making modified high alumina cement react with fluoride-containing water for 7 hours,maintaining the pH-value of fluoride-containing water to be from 6 to 8;under the above conditions,the maximum fluoride-removing rate for the solution containing 10 mg/g fluoride could reach to about 96%.
