Water pollution, especially by inorganic and organic substances, is considered as a critical problem worldwide. Several governmental agencies are listing an increasing number of compounds as serious problems in water because of their toxicity, bioaccumulation, and persistence. In recent decades, there has been considerable research on developing analytical methods of heavy metal ions and organic pollutants from water. Ionic liquids, as the environment-friendly solvents, have been applied in the analytical process owing to their unique physicochemical properties. This review summarizes the applications of ionic liquids in the determination of heavy metal ions and organic pollutants in water samples. In addition, some sorbents that were modified physically or chemically by ionic liquids were applied in the adsorption of pollutants. According to the results in all references, the application of new designed ionic liquids and related sorbents is expected to increase in the future.
水污染，尤其是由无机和有机物质造成的污染，被视为一个全球性的关键问题。由于其毒性、生物累积性和持久性，几个政府机构将越来越多的化合物列为水中的严重问题。近几十年来，在开发从水中分析重金属离子和有机污染物的方法方面进行了大量研究。离子液体作为环境友好型溶剂，因其独特的物理化学性质而被应用于分析过程。本文综述了离子液体在测定水样中重金属离子和有机污染物方面的应用。此外，一些通过离子液体进行物理或化学改性的吸附剂被应用于污染物的吸附。根据所有参考文献的结果，预计未来新设计的离子液体及相关吸附剂的应用将会增加。
