摘　　要：随着电网储能设施的建设和更新需求日益增长,铅蓄电池的更替和退运处置成为电网环保工作的重要环节。为防止铅蓄电池处置过程中的铅污染,利用天然生物质材料海藻酸钠作为基质,加入酸改性粉煤灰作为吸附活性物质,并掺杂磁性四氧化三铁作为磁性组分制备铅富集复合凝胶球。同时,研究复合凝胶球的铅离子吸附性能。结果表明:铅富集材料对于铅离子的最大吸附容量可达53.76 mg/g,吸附遵循Langmuir等温吸附模型和准二级吸附动力学模型;铅富集材料具有磁性,能够便捷地进行分离回收,为绿色零污染废弃铅蓄电池的处置提供基础。With the increasing demand for the construction and renewal of the power grid energy storage facilities,the replacement and disposal of lead-acid batteries have become an important part of the environmental protection of the grid.In order to prevent the lead pollution in the process of lead acid battery treatment,the use of natural biomass material sodium alginate as the substrate,adding acid modified fly ash as adsorption active material,and doping of magnetic Fe3O4 as a magnetic component to prepare lead enriched composite gel spheres.At the same time,the lead ion absorption characteristics of the composite gel spheres was studied.The results showed that the maximum adsorption capacity of the lead enriched materials for the maximum adsorption capacity of Pb2+can reach 53.76 mg/g,and the experimental data of the adsorption process were more fitted to the Langmuir isotherm and the pseudo-secondary adsorption dynamics model.The lead enrichment material is magnetic,can be easily separated and recycled,and provides the basis for the disposal of the green zero pollution waste lead battery.
