摘要
氟化物在自然界中广泛存在,同时人类活动也会产生大量的氟化物,进而导致水体受到不同程度的氟污染,严重威胁人类健康。在众多除氟方法中,吸附法已逐渐成为一种主要的除氟方法。其中,碳基吸附剂由于具有机械强度高、比表面积大、体积小和孔隙结构发达等特点成为研究热点之一。文章介绍了活性炭、骨炭、氧化石墨烯及碳纳米管等碳基吸附剂除氟的最新研究进展,对其性质及吸附机理等方面进行了概括总结,并对其制备成本、再生回用性能、二次污染问题及工业化应用等方面进行展望,为该领域的未来研究及应用提供一定参考。
Fluoride widely exists in nature,and human activities also produce a large amount of fluoride,which leads to different degrees of fluoride pollution in water and seriously endangers human health.Adsorption method has gradually become one of the main fluorine removal methods.Carbon-based adsorbents have become one of the research hotspots due to their high mechanical strength,large specific surface area,small volume and developed pore structure.This paper introduces the latest research progress of carbonbased adsorbents such as activated carbon,bone char,graphene oxide and carbon nanotubes for defluorination,summarizes their properties and adsorption mechanism,and prospects their preparation cost,regeneration and reuse performance,secondary pollution and industrial application,so as to provide some reference for future research and application in this field.
