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

Sequential determination of 99Tc and 126Sn in radioactive concentrate

“…The column was rinsed twice with 10 cm 3 of 2 mol•dm -3 HCl. 113 Sn was eluted with 20 cm 3 of 2 mol•dm -3 HNO 3 (Dulanská et al, 2015) and technetium was finally eluted with 20 cm 3 of 14.35 mol•dm -3 HNO 3 . Each fraction was counted on a gamma detector to check Sn and Tc behaviour on the column.…”
