High precision measurements of non-mass-dependent effects in nickel isotopes in meteoritic metal via multicollector ICPMS.
We measured the Ni isotopic composition of metal from a variety of meteorite groups to search for variations in the 60Ni abundance from the decay of the short-lived nuclide 60Fe (t(1/2) = 1.49 My) and for possible nucleosynthetic effects in the other stable isotopes of Ni. We developed a high-yield Ni separation procedure based on a combination of anion and cation exchange chromatography. Nicke...
متن کاملMass-independent fractionation of mercury isotopes in the environment
[1] The toxicity of mercury’s methylated species and its biomagnification in aquatic food chains and global dispersion by the atmosphere are the cause of worldwide health problems. Recent reports have observed natural mass-dependent fractionation in mercury isotopes, and recent theoretical work has demonstrated that isotopic separation in mercury is due primarily to nuclear field shifts (nuclea...
متن کاملMicrobiological Fractionation of Sulphur Isotopes.
A fractionation of sulphur isotopes was found in all hetabolic processes investigated except those in which elemental sulphur was the starting substrate for growth of Thiobacillus concretivorus and Chromatiurn sp. and for reduction by Saccharomyces cerevisiae. Except for polythionates formed during sulphide oxidation by T. concretivorus or Chromatiurn sp., the products of metabolism were enrich...
