First,the adsorbent was prepared by precipitation method,and XRD result show that the prepared adsorbent is cerium oxide. Then,the factors influencing the adsorption of adsorbents were investigated,and the results were used to calculate its absorption properties. The results show that the Langmuir isotherm model is more suitable in describing the adsorption process and it complies with the pseudo-second-order kinetics equation. The results of this paper provide a theoretical basis for the deep processing of phosphorus and phosphorus wastewater in industry and agriculture.%首先利用沉淀法制备了吸附剂,XRD结果表明所制备的吸附剂为氧化铈.然后对影响吸附剂吸附的各因素进行考察,并用实验结果进行计算.结果表明该吸附符合Langmuir吸附等温方程,动力学计算,结果表明其符合伪二级动力学方程.本论文结果为氧化铈对工业和农业中的含磷废水进行深度处理提供一定理论依据.
