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。
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.
