摘要
层状双氢氧化物负载生物炭(layered double hydroxides functionalized biochar,LDHs@BC)对水体中磷酸盐具有优异的吸附性能,近年来受到了广泛关注.本文详细介绍了LDHs@BC的制备方法以及制备条件对其理化性质的影响,探讨了LDHs@BC对水体中磷酸盐的吸附性能及机制,并且阐述了生物炭和层状双氢氧化物对磷酸盐吸附的协同作用及其机制,以期通过优化制备工艺参数定向调控LDHs@BC性能,显著提升LDHs@BC对磷酸盐的吸附效率.本文展望了LDHs@BC的应用前景,以期进一步推动LDHs@BC在水体修复中的应用和推广.
Layered double hydroxides functionalized biochar(LDHs@BC)has drawn wide attention for its good adsorption performance on phosphate in the aqueous system.This paper introduces the synthesis methods of LDHs@BC and summarizes the impacts of different methods on the physicochemical properties and phosphate adsorption performance.The mechanism of using LDHs@BC adsorb phosphate in the aqueous system was discussed.The synergistic mechanism of biochar and layered double hydroxides for phosphate adsorption were elucidated.The synthesis parameters could be optimized to regulate the performance of LDHs@BC,which the adsorption efficiency could be significantly enhanced.Lastly,perspectives were provided to further promote the potential application of LDHs@BC on water remediation.
