The advent of the nuclear age has given mankind the ability to synthesize new elements of higher molecular weight and number. While these man-made elements are exciting research curiosities, they are short-lived and radioactive so they are of little commercial interest from a separations standpoint at this time.
Plutonium is commercially separated using ion exchange resins but this work is only carried out by qualified laboratories under carefully controlled conditions. DuPont does not recommend the use of our resins in the highly ionizing conditions of this separation.
Uranium is 48th in abundance in the Earth's crust. It is very dense so it is used for ballistics and specialty applications. For its use in nuclear reactors, uranium must be extremely pure. Uranium is quite reactive, forming a wide range of intermetallic compounds.
