In recent years, ionic liquids have been extensively studied in the laboratory and industrial fields due to their unique properties and have shown good application prospects. At the same time, a series of ionic liquids green preparation technologies have been developed and designed, which has greatly changed the research aspect of ionic liquids. In this paper, the green preparation of ionic liquids and their application in environmental remediation are reviewed. The synthesis processes of ionic liquids, including atoms economic reaction, green raw materials reaction, green solvents reaction, chemical process intensification and computer-aided design are emphasized with reference to their advantages of high synthesis efficiency, good product quality, low waste generation, low energy consumption, mild conditions and etc. Moreover, the green preparation of ionic liquids not only makes the ionic liquid more abundant, but also makes it absolutely a green solvent and green functional material. The typical characteristics that reflect the unique advantages of ionic liquids in environmental restoration are as follows. In terms of water body restoration, it has the characteristics of high separation efficiency, elimination of secondary pollution and less consumables. In the soil remediation, it can effectively reduce the toxicity of pollutants in soil. In the atmospheric remediation, it eliminates pollutants and sometimes achieves the resource utilization. Furthermore, the future development trend of ionic liquids in green preparation and environmental remediation is also prospected.
