摘要: 水体Pb(II)污染严重危害生态环境与人类健康,吸附法是一种简单环保的Pb(II)处理技术。氧化石墨烯(GO)被认为是一种潜在的理想吸附材料,但其表面官能团种类有限、吸附选择性差、吸附后难分离等缺点制约了其实际应用。发展各种改性策略提高GO吸附性能,已成为目前研究热点。本文针对如何提高GO对水中Pb(II)的吸附效率,重点总结了N/S官能团改性、形貌改性、磁化改性三类改性策略;综述了GO基吸附剂的吸附性能,涵盖吸附容量、吸附选择性、再生性以及其他性能;详细讨论了Pb(II)吸附的四种机理,包括物理吸附、静电吸引、离子交换合表面络合;最后对GO基吸附剂去除Pb(II)进行了展望,以期为GO改性材料在Pb(II)处理方面的研究和应用提供参考依据。

Abstract: Pb(II) pollution in water constitutes a serious form of heavy metal pollution that endangers both the ecological environment and human health. As an effective sewage treatment technology, adsorption has been considered an economic and common method because of low cost, environmental friendliness and simple operation. Graphene oxide (GO), an innovative material with superior properties, has garnered extensive research as an ideal adsorbent. Nonetheless, GO faces many challenges in practical applications due to limited surface functional groups, suboptimal adsorption selectivity, and poor regenerative properties. Current research focuses on developing various modification strategies to enhance the adsorption performance of GO. In this paper, the modification methods of GO and adsorption mechanisms are reviewed. Firstly, three strategies for improving Pb(II) adsorption properties of GO-based materials are discussed, including N/S functionalization, morphological alteration and magnetization. The adsorption properties of GO-based adsorbents are evaluated, covering adsorption capacity, adsorption selectivity, regeneration, and other performance metrics. Subsequently, the adsorption mechanisms of Pb(Ⅱ) by GO-based adsorbents such as physical adsorption, electrostatic attraction, ion exchange, and surface complexation are summarized, which are essential for the development of highly efficient GO-modified materials. Finally, the future development of adsorption of GO-based materials for Pb(II) is prospected. This review provides novel insights for rational design of emerging GO-based adsorbents and serve as a reference foundation for research and application of GO-modified materials in Pb(II) treatment.
