摘要

本文综述了碳基磁性吸附剂的制备、表征、应用及其在水中无机和有机污染物吸附中的应用。描述和讨论了从活性炭、生物炭、碳氢化合物、石墨烯、碳点、碳纳米管和碳纳米笼中获得磁性吸附剂的不同制备路线,包括固体表面的磁性相。分析了这些吸附剂去除氟、砷、重金属、染料、农药、药品和其他新兴和相关的水污染物的性能。本文综述了这些吸附剂的性质及其吸附机理。总的来说,这种类型的磁性吸附剂为面对与水处理中吸附过程相关的操作问题提供了一种替代方案。然而,在这些吸附剂的物理化学特性、绿色低成本的工业生产和商业化制备方法的发展、废吸附剂的再生和最终处理以及它们在水污染物的多组分吸附中的应用等方面仍存在一些差距。

Engineered Magnetic Carbon-Based Adsorbents for the Removal of Water Priority Pollutants: An Overview
This review covers the preparation, characterization, and application of magnetic adsorbents obtained from carbon-based sources and their application in the adsorption of both inorganic and organic pollutants from water. Different preparation routes to obtain magnetic adsorbents from activated carbon, biochar, hydrochar, graphene, carbon dots, carbon nanotubes, and carbon nanocages, including the magnetic phase incorporated on the solid surface, are described and discussed. The performance of these adsorbents is analyzed for the removal of fluoride, arsenic, heavy metals, dyes, pesticides, pharmaceuticals, and other emerging and relevant water pollutants. Properties of these adsorbents and the corresponding adsorption mechanisms have been included in this review. Overall, this type of magnetic adsorbents offers an alternative for facing the operational problems associated to adsorption process in water treatment. However, some gaps have been identified in the proper physicochemical characterization of these adsorbents, the development of green and low-cost preparation methods for their industrial production and commercialization, the regeneration and final disposal of spent adsorbents, and their application in the multicomponent adsorption of water pollutants.
