Discovery of the vanadium isotopes

Abstract

a b s t r a c tTwenty-four vanadium isotopes have been observed so far and the discovery of these isotopes is discussed here. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented.

Vanadium and its isotope composition of river water and seawater: Analytical improvement and implications for vanadium isotope fractionation

“…Vanadium has only one stable isotope ( 51 V), and one very long-lived radioactive isotope ( 50 V) with a half-life time of ~1.4•10 15 years (Shore et al, 2010) which can be considered a stable isotope in isotope geochemistry. The natural 51 V/ 50 V ratio of ca.…”

Rapid determination of V isotopes with MC-ICP-MS: new developments in sample purification

“…1 As a redox-sensitive element, V is widely used to constrain variations in redox conditions in various geological processes, such as terrestrial accretion and core-mantle differentiation, 2,3 the oxidation state of the mantle and magmas throughout Earth's history, [4][5][6] as well as changes in marine palaeo-redox states. 7,8 Vanadium has two long-lived isotopes ( 50 V and 51 V) with abundances of 0.24% and 99.76%, 9 respectively. With the development of analytical methods using multi-collector inductively coupled plasma-mass spectrometry (MC-ICP-MS), high-precision measurements of V isotopes have recently been developed.…”

Determination of Vanadium Isotope Compositions in Carbonates Using an Fe Coprecipitation Method and MC-ICP-MS

“…Recently, sedimentary V isotope signatures have been advocated as a novel paleo-redox proxy. − Vanadium has two isotopes, 50 V (0.24%) and 51 V (99.76%) (Table S1). , Vanadium isotope compositions are generally reported in the δ notation (in per mil) relative to an Alfa Aesar (AA) standard solution (eq ): , …”
