Based on the adsorption performance of composite microspheres with activated carbon (AC) and sodium alginate (SA), as well as the magnetic property of Fe₃O₄, we designed and explored an efficient strategy to prepare a unique, multifunctional Fe₃O₄/AC/SA composite absorbent (MSA-AC) that extracted dye from aqueous solution. The composite exhibited the following advantages: rapid and simple to prepare, environmentally friendly process, low-cost, recyclability, and multi-functionality. The physicochemical properties of the prepared magnetic microspheres were measured, and methylene blue (MB) was selected to investigate the performance of the magnetic absorbent. The results showed a maximum adsorption capacity of 222.3 mg/g for MB. Adsorption studies revealed that the data of adsorption isotherms and kinetics fit the pseudo-second-order kinetic model and Langmuir isotherm model.
基于复合微球与活性炭（AC）和海藻酸钠（SA）的吸附性能，以及Fe₃O₄的磁性，我们设计并探索了一种高效策略，以制备一种独特的多功能Fe₃O₄/AC/SA复合吸附剂（MSA-AC），用于从水溶液中提取染料。该复合材料具有以下优点：制备快速简单、工艺环保、成本低、可回收以及多功能。对制备的磁性微球的物理化学性质进行了测定，并选择亚甲基蓝（MB）来研究磁性吸附剂的性能。结果表明，对MB的最大吸附容量为222.3 mg/g。吸附研究表明，吸附等温线和动力学数据符合准二级动力学模型和朗缪尔等温线模型。
