| 摘 要： | 本研究中利用粉煤灰合成沸石对含有Cu^2 、Pb^2 、Cd^2 的制备水样进行批处理振荡实验，其吸附容量分别为9．56、0．89和0．25mg／l。实验证明，用合成沸石处理含重金属离子污水达到平衡所需的时间约为3h。对污水中重金属离子的去除率随pH值降低而降低，随沸石用量增加而增加。同等条件下，利用粉煤灰处理含Cu^2 的污水，其吸附容量仅为6．49mg／l，低于合成沸石。

| Abstract: | In this paper,we used the synthesized zeolite from fly ash to remove Cu 2+,Pb 2+ and Cd 2+ from artificial wastewaters,the adsorption capacity of synthesized zeolite was 9.56,0.89 and 0.25mg/g respectively.Experimental results indicated,the adsorption equilibrium of using the synthesized zeolite to treat original wastewaters could be reached in about 3h,the removal rate decreased with decline of the pH,the removal rate increased with the increases of zeolite used in expeiment.Under the same condition,the adsorption capacity of fly ash was 6.49mg/g in removing the Cu 2+,lower than the zeolite synthesized from fly ash. |
