13 - Solid-phase extraction technology for actinide and lanthanide separations in nuclear fuel reprocessing

Abstract

Solid-phase extraction has become a subject of increased interest for separation applications specific to radioisotopes of the nuclear fuel cycle. The objective of this chapter is to discuss recent advances in the technology with a focus on the separations of minor actinides and lanthanides from streams associated with nuclear fuel reprocessing. The discussion covers various techniques for making solid-phase extraction resins, recent applications, separation flow sheets, column modeling and the potential advantages and disadvantages of the technology.
