Abstract
ABSTRACTAn analytical study was carried out on Eichrom resins (TRU, TEVA, UTEVA, and DGA) to identify a suitable solid phase extraction substrate to separate tin (Sn) from tellurium (Te). Standard metal solutions were spiked on batch tests in HCl and HNO3 media and the spiked analytes were determined by inductively coupled plasma mass spectrometry. The TRU resin exhibited the highest distribution coefficient (KD) for Sn in 1.0 mol L–1 HCl and the lowest KD for Te. The TRU resin charged on Bio-Rad columns showed, respectively, 99.8 ± 0.4% and 59.3 ± 1.3% Sn and Te retention, and the hydrofluoric acid (0.50 mol L–1) could wash down up to 92% of the loaded Sn, and the Te desorption can be kept as low as 5%.
