Dyes are emerging as harmful pollutants, which is one of major issues for the environmentalists and there is a urgent need for the removal of dyes from the effluents. In this context, the adsorption technology has been extensively used as an effective tool for the removal of dyes from the aqueous phase. This technique uses low-cost adsorbents and the cellulosic material is a biodegradable, cost-effective and renewable polymer, which is not soluble in the majority of solvents because of its crystalline nature and hydrogen bonding. Currently, the modified cellulosic materials for the removal of dyes from wastewater gained much attention. Moreover, the application of cellulose for water treatment can be utilized for controlling pollution and have high economic viability and availability. This review signifies the use of cellulose-based adsorbent for dyes adsorption from wastewater. The key advancement in the preparation and modification of cellulose-based adsorbents is discussed and their adsorption efficiencies are compared with other adsorbents for removal of dyes and adsorption conditions are also considered for the same. The studies reporting cellulose-based adsorption from 2003 to 2022 are included and their various properties are compared for the efficient removal of dyes. The modified cellulosic materials cellulose is a highly effective adsorbent for the remediation of effluents.
染料作为有害污染物正受到关注，这是环保主义者面临的主要问题之一，因此迫切需要从废水中去除染料。在这种情况下，吸附技术已被广泛用作从水相中去除染料的有效工具。该技术使用低成本的吸附剂，而纤维素材料是一种可生物降解、经济高效且可再生的聚合物，由于其结晶性质和氢键，它在大多数溶剂中都不溶解。目前，人们对用于从废水中去除染料的改性纤维素材料给予了极大的关注。此外，纤维素在水处理中的应用可用于控制污染，具有很高的经济可行性和可用性。本文综述了纤维素基吸附剂在从废水中吸附染料方面的应用。讨论了纤维素基吸附剂的制备和改性方面的主要进展，并将其与其他吸附剂去除染料的效率进行了比较，同时还考虑了相同条件下的吸附情况。本文纳入了 2003 年至 2022 年期间关于纤维素基吸附的研究，并对其各种性质进行了比较，以实现对染料的有效去除。改性纤维素材料是修复废水的高效吸附剂。
