Ionic liquid type crown ether derivatives, method for preparing the same and method for isolating metal ions using the same |
摘要 |
Disclosed relates to an ionic liquid type crown ether derivative, expressed by Chemical Formula 1 below, for isolating metal ions, a method for preparing the same and a method for isolating selectively the metal ions using the cycle size of the same. The present invention can provide the ionic liquid type crown ether and isolate metal ions including radioactive isotopes efficiently using the same. Furthermore, the prevent invention provides crown ether valuably used as a recyclable and environment-friendly isolating medium by preparing crown ether of ionic liquid type. wherein m, n, X− and R are identical with those in the description.
