Nonbiological fractionation of Fe isotopes: Evidence of an equilibrium isotope effect

Abstract:

Fe isotopes can be fractionated to similar extent by both biological and nonbiological processes in the laboratory. However, fractionation mechanisms are not yet clear, making it difficult to generalize from the laboratory to natural systems. We have previously shown that Fe isotope fractionations of several per mil can be generated during anion exchange chromatography of Fe dissolved in HCl. Here, we present results of experiments designed to assess the importance of equilibrium Fe isotope e...
