Abstract

Magnetic porous microspheres are widely used in modern wastewater treatment technology due to their simple and quick dye adsorption and separation functions. In this article, we prepared porous polymethylmethacrylate (PMMA) microspheres by the seed-swelling method, followed by in situ formation of iron oxide (Fe₃O₄) nanoparticles within the pore. Then, we used diazo-resin (DR) to encapsulate the porous magnetic microspheres and achieve PMMA@Fe₃O₄@DR magnetic material. We studied the different properties of magnetic microspheres by different dye adsorption experiments before and after the encapsulation and demonstrated that the PMMA@Fe₃O₄@DR microspheres can be successfully used as a reusable absorbent for fast and easy removal of anionic and aromatic dyes from wastewater and can maintain excellent magnetic and adsorption properties in harsh environments.

摘要

磁性多孔微球因其简单快速的染料吸附和分离功能而被广泛应用于现代废水处理技术中。在本文中，我们通过种子溶胀法制备了多孔聚甲基丙烯酸甲酯（PMMA）微球，随后在孔内原位形成氧化铁（Fe₃O₄）纳米颗粒。然后，我们使用重氮树脂（DR）包裹多孔磁性微球，得到PMMA@Fe₃O₄@DR磁性材料。我们通过包裹前后不同的染料吸附实验研究了磁性微球的不同性质，并证明PMMA@Fe₃O₄@DR微球可成功用作可重复使用的吸附剂，用于快速简便地从废水中去除阴离子和芳香族染料，并且在恶劣环境中仍能保持优异的磁性和吸附性能。
