Abstract
The equilibrium isotope effect in tin(II)-tin(IV) electron-exchange sy stems has been studied by a redox chromatography method using an anion -exchange resin. It was shown that the light isotopes are concentrated in tin(II) preferably. The values of the isotope separation coefficie nt (alpha) for 112Sn and heavy isotopes were determined at 82-degrees- C and 5.5 mol dm-3 HCl. The dependence of alpha on isotopic mass ratio was found to be defined by the curve reaching top values of alpha for isotopes heavier than Sn-120.
