针对白洋淀府河水体磷污染问题,研究了天然沸石、硅藻土、粉煤灰、赤泥、铁铝泥五种材料对磷的吸附性能,并利用盐酸改性铁铝泥、铁盐改性粉煤灰和赤泥,对比研究了改性后材料对磷的吸附能力,探讨了水体pH值和其他离子对其吸附性能的影响。结果表明：沸石、硅藻土、粉煤灰、赤泥对磷的吸附符合一级动力学模型,而铁铝泥和改性后材料吸附磷符合准二级动力学模型;改性前后各材料吸附磷等温线均符合Langmuir方程。各材料吸附磷能力为：改性赤泥〉改性粉煤灰〉改性铁铝泥〉铁铝泥〉赤泥和粉煤灰〉沸石〉硅藻土,改性材料吸附磷能力明显提高。“,”The adsorption capacity of natural zeolite,fly ash,red mud,diatomaceous earth,iron-aluminum mud was researched and the phosphorus adsorption of the modified adsorbents（iron-aluminum mud modified with hydrochloric acid,fly ash and red mud modified with fer
