Title: Resins for selective sorption of technetium from groundwater

Abstract

A new class of anion exchange resins with improved selectivity and sorptive capacity for the pertechnetate anion (TcO{sub 4}{sup -}) as compared to commercially available resins has been prepared and evaluated, both in batch-equilibrium and flow-through column testing conditions using a groundwater test solution. The resins have been designed and optimized for removal of pertechnetate from contaminated groundwater containing nanomolar concentrations of pertechnetate and sub-millimolar quantities of inorganic anions like nitrate, sulfate, and chloride. Equilibrium distributions coefficients for the sorption of pertechnetate to several classes of resin as a function of both time and electrolyte concentration will be discussed. The selectivity and exchange kinetics as a function of the chemical and physical structure of the resins will be addressed.
