摘要

通过吸附与原位模拟实验，研究了镧铝改性凹凸棒粘土（La/Al@ACP）对水体有机磷的吸附性能及其覆盖对沉积物磷释放的影响，并通过沉积物磷分级、DGT技术、扫描电镜能谱技术探讨材料覆盖对沉积物磷形态影响机制.结果显示，La/Al@ACP添加后，上覆水及底泥间隙水中磷含量显著下降，并伴随沉积物有效磷通量的减少.有机磷形态分析表明，添加La/Al@ACP后活性态的Lab-P_o不断向稳定态的Hum-P_o转化，有效控制了底泥磷向上覆水释放的风险.La/Al@ACP作为一种控制湖泊富营养化的有效材料，可用于底泥内源磷的固定与控制.

Abstract

Adsorption experiments and in situ simulation experiments were used to study the adsorption performance of lanthanum/ aluminum modified attapulgite clay (La/Al@ACP) on organic phosphorus in water bodies as well as the effects of its coverage on the phosphorus release from sediments. Sediment phosphorus grading, DGT technique, and scanning electron microscope energy spectrum were used to examine the material coverage mechanism on sediment phosphorus. The results showed that the phosphorus content in the overlying water, sediment, and interstitial water significantly decreased after the addition of La/Al@ACP along with a decrease in the available phosphorus flux in the sediment. Analysis of the organic form of phosphorus showed that active Lab-Po were converted to stable Hum-P_o after the addition of La/Al@ACP, which effectively controlled the risk of the release of phosphorus from the sediment to the overlying water. These results suggested that La/Al@ACP could be an effective material for controlling lake eutrophication, and be used for sediment phosphorus fixation and control.
