Chromium Isotopes and the Fate of Hexavalent Chromium in the Environment
Science, 2002Measurements of chromium (Cr) stable-isotope fractionation in laboratory experiments and natural waters show that lighter isotopes reacted preferentially during Cr(VI) reduction by magnetite and sediments. The 53 Cr/ 52 Cr ratio of the product was 3.4 ± 0.1 per mil less than that of the ...

Chromium cycle in Red Soil Critical Zone constrained by chromium isotopes
Science of The Total EnvironmentChromium (Cr) isotopic system has been used to trace Cr pollution in the modern surface environment and redox change in the paleoenvironment. However, the transformation mechanism of Cr in soil and the accompanied Cr isotopic fractionation have not been clarified clearly.

Reviews in Mineralogy and Geochemistry, 2017
Chromium consists of four stable isotopes (50Cr, 52Cr, 53Cr and 54Cr) with natural abundances of 4.35%, 83.79%, 9.50% and 2.36%, respectively (Rossman and Taylor 1998). Among these four isotopes, 50Cr, 52Cr and 54Cr are non-radiogenic, whereas 53Cr is a radiogenic product of the extinct nuclide 53Mn, which has a half-life of 3.7 Myr (Honda and Imamura ...

Spectrochimica Acta Part B: Atomic Spectroscopy, 2005
Abstract Thirty-three spectral lines of chromium atom in the blue-violet region (425–465 nm) have been investigated with the method of laser-induced resonance fluorescence on an atomic beam. For all the lines, the isotope shifts for every pair of chromium isotopes have been determined.
