Determination of 126Sn in radioactive waste using TEVA® resin and gamma spectrometry

A new method employing TEVA ® resin from Eichrom Technologies for determination of 126 Sn in nuclear waste was developed. The influence of stable tin carrier and hydrochloric acid concentration on the separation and chemical yield of 113 Sn was tested. The method is suitable for the separation of 12...

Zusammenfassung:A new method employing TEVA ® resin from Eichrom Technologies for determination of 126 Sn in nuclear waste was developed. The influence of stable tin carrier and hydrochloric acid concentration on the separation and chemical yield of 113 Sn was tested. The method is suitable for the separation of 126 Sn isotope from hydrochloric acid solution. For the determination of 126 Sn from radioactive waste samples, tin was first precipitated with ammonium sulfide in 0.5 mol L −1 HCl, dissolved in concentrated HCl, loaded in 1 mol L −1 HCl on TEVA ® resin column and eluted with 2 mol L −1 HNO 3 acid. Eluted tin fraction was directly measured by gamma spectrometry on HPGe detector.
