“…This was both due to the formation of gel-like substances on cation resin columns in 2.5 N HCl, or the need to add large amounts of ascorbic acid to reduce all Fe +3 to Fe 2+ as the former outcompetes Hf and REE in the Ln resin (Pin and Zalduegui, 1997;Münker et al, 2001). We therefore removed Fe from the matrix by solvent extraction in di-ethyl ether (Diamond and Tuck, 1960;Stichel et al, 2012). In an HCl media and at less than 8N HCl, Fe (as well as Tl, Au, Sn and Mo in our experiments) is extracted to the diethyl ether while REE, HFSE and other metals remain quantitatively in the acid.…”
