摘要
简要介绍了离子液体(ILs)在环境污染源头控制、环境污染末端治理两方面的应用及潜在危害。综述了利用离子液体进行燃料油深度脱硫、天然气中酸性气体的脱除、烟气中SO2和温室气体CO2的吸收,控制大气污染;利用离子液体去除有机废水、重金属废水及土壤中的毒害物质,净化污染水体和土壤;利用离子液体解聚废塑料,回收可利用的塑料单体,溶解和再生天然纤维等高分子材料,实现固体废弃物的资源化利用。在分析离子液体潜在危害性的基础上,提出了今后其环保应用研究的发展方向。
The application of ionic liquids in the pollution source control, end treatment and the potential hazard in the environment are summarized, including the deep desulfurization of fuel oil, removal of acid gases from crude natural gas, adsorption of flue gas and greenhouse gas by ionic liquids, which can control air pollution;the use of ionic liquids to purify the polluted water and remedy soils through extraction of hazardous contaminants from organic wastewater, heavy metal wastewater and soils;the efficient depolymerization of waste plastics to realize the recovery of monomer,the use of ionic liquids to dissolve and regenerate the natural polymer materials, such as cellulose, so that people can carry out the utilization of renewable resources. The developing direction of ionic liquids application in environmental protection is discussed on the basis of potential hazard of ionic liquids.
