Zusammenfassung:This paper describes a simple and rapid method of 99 Tc 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.
