摘  要：
[目的]研究废弃蛋壳粉对富营养化水中磷的吸附性能。[方法]在不同添加量、不同振荡时间、不同温度、不同的磷溶液初始浓度和不同溶液p H的条件下,探讨蛋壳粉对富营养化水中磷的吸附效果,考察其吸附磷的动力学行为。[结果]在含有30μg/ml的富营养化水磷溶液中,蛋壳粉的最佳添加量为10μg/ml;蛋壳粉对磷的单位吸附量随着温度的升高、磷溶液初始浓度的增加而增加;蛋壳粉在p H为5时对磷的吸附效果最佳;振荡4 h后蛋壳粉对磷的吸附量达到平衡状态;蛋壳粉对磷吸附动力学吸附过程遵循准二级动力学模型,相关系数达到0.994 3。[结论]蛋壳粉具有吸附富营养化水中磷的能力,可用于富营养化水污然治理。

摘  要：
[Objective] The research aimed to study the adsorption characteristics of abandoned egg shell powder to phosphorus in eutrophication water.[Method] Under different conditions such as the amount of eggshell powder,oscillating time,temperature,initial concentration of phosphorus solution and p H of solution,the adsorption effects of eggshell powder to phosphorus in the eutrophic water was studied,and the adsorption kinetic behavior was also studied.[Result] In the eutrophic water containing 30 μg/ml phosphorus,the optimum addition amount of eggshell powder was 10 μg/ml. The unit adsorption capacity of eggshell powder to phosphorus was increased with the increase of the initial concentration of phosphorus and temperature. The adsorption effect of eggshell powder to phosphorus was the best at p H of 5. After oscillating 4 hours,the adsorption capacity of eggshell powder to phosphorus achieved equilibrium status. The adsorption kinetics of eggshell powder to phosphorus could be described by quasi two-level dynamic model with the correlation coefficient of 0. 994 3.[Conclusion]The eggshell powder had the ability of adsorbing phosphorus,so it could be used for controlling the pollution of eutrophic water.
