摘要: 本研究以甘蔗渣为生物质模板，采用水热合成与生物质牺牲模板法制备了多孔La-Fe双金属氧化物吸附材料，并对其结构与表面性质进行了表征。结果表明，材料具有稳定的钙钛矿结构，La与Fe分布均匀，表面活性位点丰富。批量吸附实验显示，该材料对羟基乙叉二膦酸(HEDP)具有优异的去除性能，最大吸附容量为523.1 mg/g，吸附过程符合Langmuir等温模型和拟二级动力学模型。材料在酸性至中性条件下保持较高吸附效率，且对共存阴离子干扰不敏感。机理分析表明，La-O位点和晶格氧在吸附过程中起主导作用，Fe的引入通过电子结构调控增强了La位点的吸附活性。本研究为稀土–过渡金属协同吸附材料在有机膦污染治理中的应用提供了参考。
Abstract: A porous La-Fe bimetallic oxide adsorbent was synthesized using bagasse as a biomass template via a hydrothermal method combined with a sacrificial templating strategy, and its structural and surface properties were characterized. The material exhibited a stable perovskite structure with uniformly distributed La and Fe and abundant surface active sites. Batch adsorption experiments demonstrated efficient removal of hydroxyethylidene diphosphonic acid (HEDP), with a maximum adsorption capacity of 523.1 mg/g. The adsorption process followed the Langmuir isotherm model and the pseudo-second-order kinetic model. High adsorption efficiency was maintained under acidic to neutral conditions, and the effect of coexisting anions was negligible. Mechanistic analysis revealed that La-O sites and lattice oxygen dominated the adsorption process, while Fe incorporation enhanced the adsorption activity of La sites through electronic structure regulation. This study provides a reference for the application of rare earth-transition metal synergistic adsorbents in organophosphorus pollution control.
