Abstract: The speciation of the products from the reaction of 51Cr(VI) with concentrated perchloric and trifluoromethanesulfonic acids was carried out by ion chromatography, using HClO4 and Ca(ClO4)2 as eluents. The reaction (1 h) of high specific activity 51Cr(VI) with 99% CF3SO3H produces 47.6% of the 51Cr as a 3+ species (hexaaquochromium(III)), 27.6% as a 2+ species and 1.7% as a 1+ species. The reaction with 70% HClO4 gave 82.5% of the 51Cr a 3+ species, 14.0% as a 2+ species and 2.9% as a 1+ species. The 1+ and 2+ species undergo slow reactions to give the hexaaquo form.
