摘要
The present invention provides an 18-crown-6 ether derivative compound as a novel chelating ligand for supercritical extraction, a process for producing the same, and a metal extraction method using the same. According to the present invention, by using the supercritical fluid and the 18-crown-6 ether derivative, it is possible to economically and eco-friendlyly extract metal components, particularly cesium, in radioactive contaminants or radioactive wastes.
