摘要
综述了国内外金属改性生物炭吸附磷酸盐的相关研究成果,总结了金属改性生物炭的制备方法及金属改性生物炭吸附磷酸盐的能力;阐述了金属改性生物炭吸附磷酸盐的机理及解吸再生机制,分析了溶液pH值、初始磷酸盐浓度、温度、共存离子等因素对金属改性生物炭吸附磷酸盐的影响。同时,对未来研究方向进行展望,旨在为水体富营养化治理提供科学依据和理论基础。
The related research results of phosphate adsorption by metal-modified biochar at home and abroad are reviewed,and the preparation method of metal-modified biochar and the ability of metal-modified biochar to adsorb phosphate are summarized;mechanism and desorption regeneration mechanism,analyzed the influence of pH value,initial phosphate concentration,temperature,coexisting ions and other factors on the adsorption of phosphate by metal modified biochar.At the same time,the prospects for future research directions are aimed at providing scientific and theoretical basis for water eutrophication management.
