摘　　要：为解决我国高氟区农村和小城镇居民饮用水氟超标的问题,提供开发高效实用的小型高氟饮用水处理装置的技术参数,采用静态震荡方式以及氟离子选择电极法研究了吸附剂——人造沸石的NH4Cl-FeCl3和NH4Cl-KAl(SO4)2改性方法。结果表明,人造沸石经质量分数分别为3%的氯化铵溶液活化,和5%的氯化铁溶液或4%的硫酸铝钾溶液改性后除氟效果最佳,可使氟离子质量浓度为20～100 mg·L-1的高氟水在8～12 h内达到GB 5749-2006要求。人造沸石NH4Cl-KAl(SO4)2改性方法优于NH4Cl-FeCl3。方法操作简单、成本较低、易于推广。In order to solve the problem of drinking water with excessive fluoride in high fluoride areas in rural and small towns,provide scientific basis for the development of efficient and practical small set for treating high-fluoride drinking water.The modification methods on artificial zeolite by NH4Cl-FeCl3 and NH4Cl-KAl（SO4）2 were studied by the experiment.The high-fluoride water with F-concentration of 20～100 mg·L^-1,can be treated to meet the requirements of drinking water standards in 8～12 h by modified artificial zeolite which was immersed in 3% NH4Cl solution and 5% FeCl3 solution or 3% NH4Cl solution and 4% KAl（SO4）2 solution.Results show that F-removal performance of artificial zeolite modified by NH4Cl-KAl（SO4）2 excels that by NH4Cl-FeCl3,and it is low cost,easy to operate.
