新出现的污染物（CEC）是一类可能对环境和人类造成风险的新型污染物。此类污染物在环境中普遍存在，因为其顽固性，无法通过传统的废水排放处理方法轻易地完全消除。吸附是一种高效、直接、方便、相对便宜且可持续的技术，可用于大规模去除水中的 CEC。最近发表了许多关于生物炭及其复合材料的评论文章，这些生物炭及其复合材料源自几种农业废物源，用于通过吸附去除水中的有机污染物。然而，CEC 在各种生物基吸附剂上吸附的详细机制却鲜有报道。此外，生物基吸附剂的再生和稳定性需要具体考虑。目前的工作整理了过去几十年关于生物基吸附剂及其复合材料用于去除 CEC 的研究报告，旨在深入了解生物基吸附剂的吸附、再生和稳定性机制，使研究人员能够设计一种生物基吸附剂。基于吸附剂的可持续去除水中的 CEC。还讨论了生物基吸附剂的优点和缺点。最后，提出了一些关键建议，以改善使用生物基吸附剂从水中去除 CEC。生物基吸附剂的再生和稳定性，使研究人员能够设计一种生物基吸附剂，以可持续地去除水中的 CEC。还讨论了生物基吸附剂的优点和缺点。最后，提出了一些关键建议，以改善使用生物基吸附剂从水中去除 CEC。生物基吸附剂的再生和稳定性，使研究人员能够设计一种生物基吸附剂，以可持续地去除水中的 CEC。还讨论了生物基吸附剂的优点和缺点。最后，提出了一些关键建议，以改善使用生物基吸附剂从水中去除 CEC。

Recent advances on sustainable removal of emerging contaminants from water by bio-based adsorbents

Contaminants of emerging concern (CECs) are a new class of pollutants that may pose environmental and human risks. Such contaminants are prevalent in the environment as they can’t be easily eliminated completely by traditional processing of wastewater discharge due to their obstinate nature. Adsorption is one such technique that is efficient, straightforward, convenient, comparatively inexpensive and sustainable for removing CECs from water on a large scale. Many review articles have been published recently on biochar and its composites derived from several agricultural waste sources for the removal of organic contaminants from water by adsorption. However, a detailed mechanistic aspect of adsorption of CECs on various bio-based adsorbents is scarcely reported. Additionally, the regeneration and stability of bio-based adsorbents need specific consideration. The present work collates studies reported in the last couple of decades on bio-based adsorbents and their composites for CEC removal with the aim to provide insights into the mechanism of adsorption, regeneration and stability of bio-based adsorbents to enable researchers to design a bio-based adsorbent for sustainable removal of CECs from water. The advantages and disadvantages of bio-based adsorbents are also argued. In the end, some key recommendations are made to improve CEC removal from water using bio-based adsorbents.
