| 摘 要： | 粉煤灰用适量亚铁离子改性后对磷的吸附能力有明显改善。温度是影响吸附效果的重要因素，温度升高有利于粉煤灰对磷酸根的吸附。含磷50mg／L的溶液投加改性粉煤灰的量为2．5％，3．5％时磷的吸附效率达98％、99％以上，溶液含磷量降至1mg／L、0．5mg／L以下。

| Abstract: | The fly ash modified by Fe~(2+) has more sorption to phosphate.Temperature is the dominant factor to affect the adsorption result.Adsorbent doses of modified fly ash from 2.5 to 3.5g/100mL produced over 98% and 99% removal of phosphate(50mg P/L),which can reduce concentration of phosphorus to 1mg/L and 0.5mg/L. |

| Keywords: | fly ash adsorption phosphate modified Fe~(2+) ferrous sulphate |
