Abstract
We report oxygen isotope fractionation of dissolved oxygen during reduction by Fe(II). Ferrous sulfate is dissolved in 60ml of water, and the reaction bottles were kept at 23, 40, and 54C. The headspace samples were extracted using gastight syringe and injected into EA/IRMS to measure concentration and isotope composition of oxygen molecule. The reduction rate of oxygen molecule increases with the increase of the reaction temperature and ferrous sulfate amounts. In contrast, oxygen isotope fractionation factor becomes smaller with the increase of reaction rate.
