This article discusses the potential applications of natural polysaccharide-based graphene oxide nanomaterials in the field of wastewater remediation through the removal of organic and synthetic dyes. Being highly toxic, carcinogenic, and nonbiodegradable, dyes disposed from textile, paper, and printing industries etc. pose a serious threat to various life forms on earth. Recently, there has been an increased interest in the amalgamation of biopolymers, such as polysaccharides, with the high adsorption efficiency of graphene oxide. Polysaccharides, apart from being nontoxic, low cost, and eco-friendly, possess a variety of functional groups enabling them to be easily tuned for the desired applications. When grafted with GO nanosheets, they give rise to unique nanomaterials possessing diverse applications, especially in the eradication of harmful contaminants from wastewater. This review is an attempt to give consolidated and detailed information on different aspects of the adsorption behavior of various potentially low-cost polysaccharide-based GO nanoadsorbents toward lethal dyes. The characterization techniques used, adsorption isotherms, kinetics, thermodynamic behavior, recyclability, and swelling properties as well as the adsorption mechanism have been outlined in this article. The whole anthology of literature reports excellent dye removal efficiency with significant regeneration performance making these nanoadsorbents promising candidates for practical applications. In view of all aspects, this review recommends the use of such sustainable adsorbents with a further search toward obtaining the polysaccharides from natural wastes.

天然多糖基氧化石墨烯纳米复合材料用于去除染料的研究进展
本文讨论了基于天然多糖的氧化石墨烯纳米材料在通过去除有机和合成染料的废水修复领域中的潜在应用。来自纺织，造纸和印刷行业的染料具有剧毒，致癌性和不可生物降解性，对地球上的各种生命形式构成了严重威胁。近来，人们对具有诸如氧化石墨烯的高吸附效率的生物聚合物例如多糖的合并的兴趣增加。多糖除无毒，低成本和环保外，还具有多种功能基团，可轻松针对所需应用进行调整。当用GO纳米片接枝时，它们会产生具有多种用途的独特纳米材料，特别是在消除废水中的有害污染物方面。这项审查是试图提供有关各种潜在的低成本基于多糖的GO纳米吸附剂对致死染料的吸附行为的不同方面的综合和详细的信息。本文概述了所使用的表征技术，吸附等温线，动力学，热力学行为，可回收性和溶胀性以及吸附机理。整个文献集都报告了出色的染料去除效率和显着的再生性能，这些纳米吸附剂有望成为实际应用的候选材料。从各个方面来看，本综述建议使用这种可持续的吸附剂，并进一步寻求从天然废物中获得多糖。
