Water is the most important and essential component of earth's ecosystem playing a vital role in the proper functioning of flora and fauna. But, our water resources are contaminating continuously. The whole world may be in great water scarcity after few decades. Graphene, a single-atom thick carbon nanosheet, and graphene nanomaterials have bright future in water treatment technologies due to their extraordinary properties. Only few papers describe the use of these materials in water treatment by adsorption, filtration, and photodegradation methods. This article presents a critical evaluation of the contribution of graphene nanomaterials in water treatment. Attempts have been made to discuss the future perspectives of these materials in water treatment. Besides, the efforts are made to discuss the nanotoxicity and hazards of graphene-based materials. The suggestions are given to explore the full potential of these materials along with precautions of nanotoxicity and its hazards. It was concluded that the future of graphene-based materials is quite bright.
水是地球生态系统中最重要和最基本的组成部分，对动植物的正常功能起着至关重要的作用。但是，我们的水资源正在不断受到污染。几十年后，全世界可能会面临严重的水资源短缺。由于具有非凡的特性，单层原子厚的碳纳米薄片石墨烯和石墨烯纳米材料在水处理技术中有广阔的应用前景。只有少数几篇论文描述了这些材料通过吸附、过滤和光降解方法在水处理中的应用。本文对石墨烯纳米材料在水处理中的贡献进行了批判性评价。尝试讨论了这些材料在水处理中的未来前景。此外，还努力讨论了基于石墨烯的材料的纳米毒性和危害。提出了一些建议，以探索这些材料的全部潜力，并注意纳米毒性及其危害。结论是，基于石墨烯的材料的前景非常光明。
