Abstract

Emerging contaminants (ECs) pose significant environmental risks. They also present health hazards due to their persistence and resistance to degradation. Membrane separation has emerged as a promising technique for ECs removal, offering high precision and minimal secondary pollution. However, conventional membranes face challenges like selectivity-permeability trade-offs and fouling, limiting their effectiveness. Recent advancements involve incorporating two-dimensional (2D) materials such as graphene oxide (GO) and MXene into polymer membranes through layer-by-layer stacking or as additives to enhance the overall performance. While existing reviews generally cover the importance of membrane technologies and the role of 2D materials, there is a lack of comprehensive analysis focusing on the specific challenges and the innovative integration of 2D materials to address these challenges. This review discusses various methods of membrane modification using typical 2D materials, along with the latest research findings on novel composite membranes for the separation and degradation of different types of ECs in wastewater. Furthermore, it summarizes the removal mechanisms of these innovative membranes for ECs, providing valuable insights for the future development of high-performance membranes based on 2D materials.

基于二维材料的高性能膜，用于去除水系统中新出现的污染物：进展与挑战

新出现的污染物（ECs）对环境构成重大风险。由于其持久性和抗降解性，它们还对健康造成危害。膜分离技术具有精度高、二次污染小等优点，已成为一种很有前景的去除 ECs 的技术。然而，传统膜面临着选择性-渗透性权衡和污垢等挑战，限制了其有效性。最近的进展涉及通过逐层堆叠或作为添加剂将氧化石墨烯（GO）和 MXene 等二维（2D）材料纳入聚合物膜，以提高整体性能。虽然现有的综述一般都涵盖了膜技术的重要性和二维材料的作用，但缺乏侧重于具体挑战和二维材料创新整合以应对这些挑战的全面分析。本综述讨论了使用典型二维材料进行膜改性的各种方法，以及新型复合膜用于分离和降解废水中不同类型的 ECs 的最新研究成果。此外，它还总结了这些创新膜对氨基甲酸乙酯的去除机制，为未来开发基于二维材料的高性能膜提供了宝贵的见解。
