Contamination of the aqueous environment caused by the presence of heavy metal ions and oils is a growing concern that must be addressed to reduce their detrimental impact on living organisms and safeguard the environment. Recent efficient and environmentally friendly remediation methods for the treatment of water are based on third-generation bioaerogels as emerging applications for the removal of heavy metal ions and oils from aqueous systems. The peculiarities of these materials are various, considering their high specific surface area and low density, together with a highly porous three-dimensional structure and tunable surface chemistry. This review illustrates the recent progress in aerogels developed from cellulose and chitosan as emerging materials in water treatment. The potential of aerogel-based adsorbents for wastewater treatment is reported in terms of adsorption efficacy and reusability. Despite various gaps affecting the manufacturing and production costs of aerogels that actually limit their successful implementation in the market, the research progress suggests that bio-based aerogels are ready to be used in water-treatment applications in the near future.
由重金属离子和油类的存在所导致的水环境污染是一个日益受到关注的问题，必须加以解决，以减少它们对生物的有害影响并保护环境。近期用于水处理的高效且环保的修复方法基于第三代生物气凝胶，这是从水体系中去除重金属离子和油类的新兴应用。这些材料的特性多种多样，考虑到它们具有高比表面积、低密度，以及高度多孔的三维结构和可调节的表面化学性质。本综述阐述了由纤维素和壳聚糖制备的气凝胶作为水处理新兴材料的最新进展。基于气凝胶的吸附剂用于废水处理的潜力在吸附效率和可重复使用性方面进行了报道。尽管存在各种影响气凝胶制造和生产成本的差距，这些差距实际上限制了它们在市场上的成功应用，但研究进展表明，生物基气凝胶在不久的将来准备好用于水处理应用。
