The adsorption of Cf, Es, and Fm on several metals was studied thermochromatographically. In all systems investigated Es is adsorbed between the Cf and Fm, due to the increasing metallic divalency in the second half of the actinide series. Based on t

Publikováno v: J. Alloys and Compounds 271-273, 307 (1998)

The sorption was studied of element 104 (rutherfordium, Rf) and thorium on the strongly acidic cation exchanger DOWEX 50×8. The experiments were carried out on-line. Rf is strongly retained on cation exchange resins from diluted HCl/HF solutions in

Untersuchungen des Triiodidgleichgewichtes in wäßriger Lösung mit der horizontalen Zonenelektromigration

Autor: St. Taut, R. Dreyer, Steffen Fischer

Publikováno v: Isotopenpraxis Isotopes in Environmental and Health Studies. 27:139-143

Using the electromigration method in free electrolyte solution for characterisation of the polyiodide equilibrium the influence of isotope exchange on the electromigration behaviour was studied. A special electromigration equation was derived. Based
