英文摘要	The extraction of strontium ions using DCH18C6 as the extractant and various ionic liquids (ILs) as solvents has been investigated. The distribution ratio of Sr(2+) can reach as high as 10(3) under certain conditions, much larger than that in DCH18C6/n-octanol system. The extraction capacity depends greatly on the structure of ionic liquids. In Ils-based extraction systems, the extraction efficiency of strontium ions is reduced by increasing the concentration of nitric acid and can also be influenced directly by the presence of Na(+) and K(+) in the aqueous phase. It is confirmed that the extraction proceeds mainly via a cation-exchange mechanism.
