摘要
天然佛石经活化后，对废水中的Pb(2+)有较强的吸附作用。结果表明，吸附剂504用量10g／LH2O，吸附120分钟．为适宜的反应条件。当Pb(2+)浓度为207mg／L时，吸附率可达99．5％，吸附容量为32．03mg／g且较好地符合Freundlich吸附等温式：Q＝5．56C1.84。
By activation treatment, natural zeolite can absorb Pb(2+) in waste water significantly. The result shows that the ap-propriate reaction conditions should be the ratio of 504 absorbentto water being 10g/L,. pH = 2, absorbent reaction time 120 min.when waster water is treated on Pb(2+) 207mg/L, the removal effi-cience of Pb(2+) is 99. 5 %. The absorbance is 32. 03mg/g. The ab-sorption process was conformed to Freundliceh isothemal line Q=5. 56C1.84.
