摘　　要：研究了经不同方法改性方沸石的除氟效果,并对搅拌吸附时间、高氟水含氟量、硫酸根离子浓度和pH值等对改性方沸石除氟的影响作了研究。结果表明,先高温活化,后用硫酸铝钾溶液活化处理的方沸石,以1g改性方沸石加入100mL含氟5mg/L的模拟饮用高氟水做吸附试验,在模拟高氟水pH值为6.5、搅拌时间20min时,沸石的吸附量达420μg/g以上,吸附后模拟高氟水残余氟含量降至1mg/L以下,达到国家饮用水标准要求。The defluorination effect of different way modified analcime was studied.And the influence of the adsorbed time, the sulfate radical ion and the pit-value to the defluorination were researched. The results indicated that, the Ig analcime modified by high temperature and aluminum sulfate for 100ml water with fluorin 5mg/L,when the pH-value was 6.5, after 20 minutes absorb, the absorb quantity to fluorin was reached 420μg/g. Residual fluorine content is under 1ing/L, it was meet national standard of drinking water.
