Polymers derived from plant and animal sources are of great interest in wastewater remediation due to their cost-effectiveness and renewable adsorption capabilities, one such polymer is nanocellulose (NC). NC has gained a lot of attention in various research fields due to its abundance in nature, nano-dimension, high surface area, stability and bio-compatibility. As a result, NC has emerged as a great potential adsorbent for the removal of contaminants such as heavy metals, organic dyes, oils, pharmaceutical and etc. in the environmental remediation. This review focuses on the description of the building blocks, structure, properties, isolation and also discusses the potential of nanocellulose based composites materials with reinforcements such as activated carbon, carbon nanotube, graphene oxides, metals, non-metals and ceramics that were effectively used as an adsorbents for diverse organic and inorganic contaminants in water.
基于动植物来源的聚合物由于其成本效益和可再生吸附能力，在废水修复中引起了极大的关注，其中一种聚合物是纳米纤维素（NC）。由于其在自然界中的丰富性、纳米尺寸、高表面积、稳定性和生物相容性，NC 在各个研究领域引起了广泛关注。因此，NC 已成为去除环境修复中污染物（如重金属、有机染料、油类、药物等）的潜在高效吸附剂。本文综述了 NC 的构建块、结构、性能、分离的描述，并讨论了基于纳米纤维素的复合材料的潜力，其中包括活性炭、碳纳米管、氧化石墨烯、金属、非金属和陶瓷等增强材料，这些材料有效地用作水中各种有机和无机污染物的吸附剂。
