【摘要】 工业化的迅速发展，导致水体中的重金属污染日益严重，不仅对自然环境的可持续发展提出了严峻考验，也严重威胁着人类的健康。治理铬[Cr(Ⅵ)]污染的众多方法中，吸附法因其环保、高效、可循环再生、无二次污染等优点，被认为是一种极具应用前景的方法。木质素碳和水热活化法获得的碳材料中均含有大量官能团，对去除废水中的Cr(Ⅵ)具有巨大潜力。本文综述了改性木质素基吸附剂和水热活化碳去除Cr(Ⅵ)的研究进展及存在的问题，展望了提高吸附剂吸附效率的方法和实现吸附剂工业化应用的途径。更多还原

【Abstract】 The rapid development of industrialization has led to increasingly serious heavy metal pollution in water bodies, which not only poses a severe test for the sustainable development of the natural environment but also seriously threatens human health.Among the methods for treating Cr(Ⅵ) pollution, adsorption is considered as a very promising method because of its advantages of environmental protection, high efficiency, recyclable regeneration, and no secondary pollution. Both lignin-based adsorbent and carbon materials obtained by hydrothermal activation contain a large number of functional groups, which have great potential for the removal of Cr(Ⅵ) from wastewater. This paper reviewed the research progress and existing problems of Cr(Ⅵ) removal by modified lignin-based adsorbents and hydrothermal activated carbon and prospected methods to improve the adsorption efficiency of adsorbents and the ways to realize the industrial application of adsorbents.更多还原
