Please join us Thursday, Feb. 9 at 11 a.m. EST in WAN305 for the talk, Understanding Extraction Chromatography Materials for f-element Separations by Erin R. Bertelsen, Assistant Professor, Department of Physics and Applied Physics, UMass Lowell.

Abstract

This presentation will highlight the use and manipulation of extraction chromatographic supports for f element separations. The lanthanides and trivalent actinides are some of the most difficult elements to separate from one another, yet the need for their separation spans multiple applications, including technologies using rare earth elements, nuclear forensics, and nuclear fuel reprocessing. Our group emphasizes material manipulation, instead of novel extractants, to advance our understanding of chromatographic separations for radioactive elements. The relatively stability of diatomaceous earth supports after gamma irradiation, as well as synergistic and antagonistic effect on europium partitioning using multi-extractant chromatography materials, will be discussed.

Light refreshments will be served. Please RSVP to Lynne_Schaufenbil@uml.edu if you plan to attend.
