摘要
利用水泥对电厂粉煤灰进行改性 ,并将改性粉煤灰应用于去除废水中的磷 ,探讨了吸附平衡时间、吸附剂用量、颗粒的大小、p H值以及初始浓度等对吸附效率的影响。在最佳条件下 ,磷的去除率可以达到
A modified fly ash adsorbent was prepared and applied for the removal of phosphate in water. Experimental results showed that the initial concentration, adsorption time, pH and particle size were the influence factors on the removal rate of phosphate. Under the optimum conditions, the removal rate could be more than 95%.
