摘　　要：为了研究颗粒状粉煤灰基质滤料对于水体中的可溶性Cu2+的吸附性能,主要探讨了滤料的投加量、吸附时间、操作温度等对吸附效果的影响。结果表明,在20℃,初始浓度为10 mg/L的含铜溶液中,当滤料投加量为800 g/L,振荡速率为110 r/min,经过25 min后,吸附率可达91.53%。温度升高有利于Cu2+去除率的提高和单位吸附量增加,但超过65℃后变化不明显。In order to study the adsorption characteristics of grainy fly ash filter material to Cu2＋ in water,the effect of filter material dosage,absorption time and operation temperature were investigated.The results showed the adsorption ratio of Cu2＋ could reach 91.53%,the solution with 10 mg/L initial concentration on the operation condition of 800 g/L dosage,20 ℃ and stirring speed of 110 r/min for 25 min.The rise of operation temperature was beneficial to the increase of removal ratio and adsorption capacity,which was not obvious when the temperature exceeded 65 ℃.
