| 摘 要： | 通过研究改性海泡石对磷的吸附性能,确定了除磷剂用量、温度、含磷废水流量、添加剂等因素对改性海泡石磷吸附热力学平衡的影响.研究结果表明:改性海泡石除磷剂对废水中PO43-离子的吸附容量随除磷剂质量的增加而减小;去除率随除磷剂用量的增加而增大;提高酸改性温度有利于复合除磷剂对磷的吸附;除磷剂的吸附量随海泡石焙烧温度的提高而...

| Abstract: | The modification of sepiolite as well as preparation and adsorptive capacity of phosphorus were discussed.The methods used for modification for sepiolite involved single acid activation.Effects of phosphorus remover dosage,temperature,phosphorus current velocity on the adsorption capacity were experimentally investigated,which provided a thermodynamic basis for phosphorus removal industrialization in sepiolite. |
