Water pollution is one of the most aggravated problems threatening the sustainability of human race and other life forms due to the rapid pace of civilization and industrialization. A long history exists of release of hazardous pollutants into the water bodies due to selfish human activities since the Industrial Revolution, but no effort has been completely successful in curbing the activities that result in the degradation of our environment. These pollutants are harmful, carcinogenic and have adverse health effects to all forms of life. Thus, remarkable efforts have been geared up to obtain clean water by exploiting science and technology. The application of Ionic liquids (ILs) as sustainable materials have received widespread attention since the last decade. Their interesting properties, simplicity in operation and satisfactory binding capacities in elimination of the contaminants makes them a valuable prospect to be utilized in wastewater treatment. Immobilizing and grafting the solid supports with ILs have fetched efficient results to exploit their potential in the adsorptive removal processes. This review provides an understanding of the recent developments and outlines the possible utility of IL based nano adsorbents in the removal of organic compounds, dyes and heavy metal ions from aqueous medium. Effect of several parameters such as sorbent dosage, pH and temperature on the removal efficiency has also been discussed. Moreover, the adsorption isotherms, thermodynamics and mechanism are comprehensively studied. It is envisioned that the literature gathered in this article will guide the budding scientists to put their interest in this area of research in the days to come.
水污染是威胁人类和其他生命形式可持续性的最严重问题之一，这是由于文明和工业化的快速发展。自工业革命以来，由于人类的自私活动，大量危险污染物被排放到水体中，但没有任何努力能够完全成功地遏制导致环境恶化的活动。这些污染物是有害的、致癌的，对所有生命形式都有不良的健康影响。因此，人们已经做出了巨大的努力，通过利用科学和技术来获得清洁水。离子液体（ILs）作为可持续材料的应用自上十年以来受到了广泛关注。它们有趣的性质、操作简单以及在消除污染物方面令人满意的结合能力，使它们成为在废水处理中利用的有价值的前景。将固体载体固定和接枝到 ILs 上已经取得了有效的结果，以开发它们在吸附去除过程中的潜力。这篇综述提供了对最新发展的理解，并概述了基于 IL 的纳米吸附剂在从水介质中去除有机化合物、染料和重金属离子方面的可能应用。还讨论了吸附剂用量、pH 值和温度等几个参数对去除效率的影响。此外，还综合研究了吸附等温线、热力学和机理。预计本文收集的文献将指导未来有抱负的科学家对这一研究领域产生兴趣。
