Water pollution by heavy metals, dyes, and antibiotics is a serious environmental problem. Efficient and recyclable adsorbents are needed. Magnetic nanocomposite adsorbents (MNAs) offer a promising solution. They combine magnetic nanoparticles with various carriers. This gives them high adsorption capacity and easy magnetic separation. This review covers recent progress in MNAs. We focus on three carrier types: carbon-based materials, inorganic minerals, and natural polymers. We analyze common synthesis methods like co-precipitation and hydrothermal synthesis. The synergy between components enhances pollutant removal, however, challenges remain. These include poor selectivity in mixed pollutants and difficult large-scale production. Stability during reuse is also a concern. Future work should aim for greener synthesis and better stability. This review provides useful insights for designing high-performance MNAs for water treatment.
重金属、染料和抗生素造成的水污染是一个严重的环境问题。需要高效且可回收的吸附剂。磁性纳米复合吸附剂（MNAs）提供了一个有前景的解决方案。它们将磁性纳米颗粒与各种载体结合在一起。这赋予了它们高吸附容量和易于磁分离的特性。本综述涵盖了MNAs的最新进展。我们重点关注三种载体类型：碳基材料、无机矿物和天然聚合物。我们分析了共沉淀和水热合成等常见的合成方法。各组分之间的协同作用增强了污染物的去除效果，然而，挑战依然存在。这些挑战包括对混合污染物的选择性差以及大规模生产困难。重复使用期间的稳定性也是一个问题。未来的工作应致力于更绿色的合成和更好的稳定性。本综述为设计用于水处理的高性能MNAs提供了有用的见解。
