| Abstract: | This paper describes a simple and rapid method of 99Tc pre-concentration, separation and purification by using AnaLig? Tc02 gel in two stages or AnaLig? Tc02 gel in a first stage and TEVA? resin in a second stage, which are commercially available from IBC advanced technologies, Inc. and Eichrom technologies,
Inc., respectively. The method is suitable for analyzing large volume concentrate samples in a relatively short time. The
use and effectiveness of AnaLig? Tc02 and Eichrom’s TEVA? resin were successfully tested by analysis of evaporator concentrate samples which belong to the class of most difficult
matrices to analyze. |
