Many environmental pollutants caused by uncontrolled urbanization and rapid industrial growth have provoked serious concerns worldwide. These pollutants, including toxic metals, dyes, pharmaceuticals, pesticides, volatile organic compounds, and petroleum hydrocarbons, unenviably compromise the water quality and manifest a severe menace to aquatic entities and human beings. Therefore, it is of utmost importance to acquaint bio-nanocomposites with the capability to remove and decontaminate this extensive range of emerging pollutants. Recently, considerable emphasis has been devoted to developing low-cost novel materials obtained from natural resources accompanied by minimal toxicity to the environment. One such component is cellulose, naturally the most abundant organic polymer found in nature. Given bio-renewable sources, natural abundance, and impressive nanofibril arrangement, cellulose-reinforced composites are widely engineered and utilized for multiple applications, such as wastewater decontamination, energy storage devices, drug delivery systems, paper and pulp industries, construction industries, and adhesives, etc. Environmental remediation prospective is among the fascinating application of these cellulose-reinforced composites. This review discusses the structural attributes of cellulose, types of cellulose fibrils-based nano-biocomposites, preparatory techniques, and the potential of cellulose-based composites to remediate a diverse array of organic and inorganic pollutants in wastewater.
由无节制的城市化和快速的工业增长所导致的许多环境污染物，已引起全球范围内的严重关注。这些污染物，包括有毒金属、染料、药物、农药、挥发性有机化合物和石油烃，不可避免地损害了水质，并对水生生物和人类构成了严重威胁。因此，使生物纳米复合材料具备去除和净化这类广泛的新兴污染物的能力至关重要。最近，人们相当重视开发源自自然资源且对环境毒性最小的低成本新型材料。其中一种成分是纤维素，它是自然界中天然存在的最丰富的有机聚合物。鉴于其生物可再生来源、天然丰富性以及令人印象深刻的纳米纤维排列，纤维素增强复合材料被广泛设计并应用于多种用途，如废水净化、储能装置、药物递送系统、造纸和纸浆工业、建筑工业以及粘合剂等。环境修复前景是这些纤维素增强复合材料的迷人应用之一。本综述讨论了纤维素的结构特性、基于纤维素原纤维的纳米生物复合材料的类型、制备技术，以及纤维素基复合材料在修复废水中各种有机和无机污染物方面的潜力。
