The supply of affordable drinking and sufficiently clean water for human consumption is one of the world's foremost environmental problems and a large number of scientific research works are addressing this issue Various hazardous/toxic environmental contaminants in water bodies, both inorganic and organic (specifically heavy metals and dyes), have become a serious global problem. Nowadays, extensive efforts have been made to search for novel, cost effective and practical biosorbents derived from biomass resources with special attention to value added, biomass-based renewable materials. Lignin and (nano)material adorned lignin derived entities can proficiently and cost effectively remove organic/inorganic contaminants from aqueous media. As low cost of preparation is crucial for their wide applications in water/wastewater treatment (particularly industrial water), future investigations must be devoted to refining and processing the economic viability of low cost, green lignin-derived (nano)materials. Production of functionalized lignin, lignin supported metal/metal oxide nanocomposites or hydrogels is one of the effective approaches in (nano)technology. This review outlines recent research progresses, trends/challenges and future prospects about lignin-derived (nano)materials and their sustainable applications in wastewater treatment/purification, specifically focusing on adsorption and/or catalytic reduction/(photo)degradation of a variety of pollutants.
为人类提供可负担得起的饮用水和足够清洁的水是世界上面临的首要环境问题之一,大量的科学研究工作正在解决这个问题。水体中的各种有害/有毒环境污染物,包括无机和有机污染物(特别是重金属和染料),已成为一个严重的全球性问题。如今,人们已经做出了广泛的努力,从生物质资源中寻找新型、具有成本效益和实用的生物吸附剂,特别关注附加值、基于生物质的可再生材料。木质素和(纳米)材料修饰的木质素衍生实体可以有效地、具有成本效益地从水介质中去除有机/无机污染物。由于制备成本低对于它们在水/废水处理(特别是工业用水)中的广泛应用至关重要,因此未来的研究必须致力于改进和加工低成本、绿色木质素衍生(纳米)材料的经济可行性。功能化木质素的生产、木质素负载的金属/金属氧化物纳米复合材料或水凝胶的生产是(纳米)技术中的有效方法之一。本综述概述了关于木质素衍生(纳米)材料及其在废水处理/净化中的可持续应用的最新研究进展、趋势/挑战和未来展望,特别是重点关注各种污染物的吸附和/或催化还原/(光)降解。
