摘　　要：常温下,用硫酸铝为改性剂制得改性粉煤灰,以此作为有机磷废水的吸附剂,用分光光度法分析改性粉煤灰对有机磷的吸附性能,并通过XRD对其结构进行表征。结果表明:改性时,盐灰质量比为1∶12;吸附时,改性粉煤灰用量为35g/L、溶液的pH值为8、振荡时间为30min、吸附温度为30℃时,磷的去除率可达97.0%。With aluminum sulfate as modifier,the modified fly ash was prepared that was as the adsorbent of organic phosphates waste water at room temperature,and the absorption performance of the modified fly ash on organic phosphates was analyzed by spectrophotometry,and the structure was characterized by XRD.The removal rate of phosphate could reach 97%,when the mass ratio of aluminum sulfate to fly ash was 1∶12,the amount of the modified fly ash was 35g/L,the value of pH was 8,the adsorption time was 30min and the absorption temperature was 30 ℃.
