Cellulose-based sorbents are promising materials for wastewater treatment due to their environmental friendliness, biodegradability, and high sorption capacity. This paper presents an overview of cellulose modification methods, including carboxylation, amination, oxidation, graphene, and plasma treatments, as well as combined approaches. Their effect on key physicochemical properties, such as porosity, morphology, and chemical stability, is considered. Examples from the literature confirm the effectiveness of modified cellulose sorbents in removing heavy metal ions and organic pollutants from wastewater. The analysis shows that combined methods allow for creating materials with improved characteristics that are resistant to extreme operating conditions. The main advantages and disadvantages of cellulose sorbents, as well as challenges associated with their scalability and cost-effectiveness, are discussed. The paper emphasizes the importance of further research to advance these materials as a key element of sustainable water treatment technologies.
基于纤维素的吸附剂因其环境友好性、生物可降解性和高吸附容量，是用于废水处理的有前景的材料。本文概述了纤维素改性方法，包括羧基化、胺化、氧化、石墨烯和等离子体处理，以及组合方法。考虑了它们对关键物理化学性质（如孔隙率、形态和化学稳定性）的影响。文献中的例子证实了改性纤维素吸附剂在去除废水中重金属离子和有机污染物方面的有效性。分析表明，组合方法能够制备出具有改进特性且能耐受极端操作条件的材料。讨论了纤维素吸附剂的主要优缺点，以及与其可扩展性和成本效益相关的挑战。本文强调了进一步研究的重要性，以推动这些材料成为可持续水处理技术的关键要素。
