Abstract
In dilute acetic acid solutions, U(VI) shows a useful chromatographic distribution on DEAE-cellulose layers, while most other metal ions migrate upwards to the solvent front or remain at or near the start. This chromatographic behaviour of U(VI) enables a selective method for the separation of U(VI) by thin-layer chromatography to be developed. The R F values on DEAE-cellulose and Avicel SF are quoted for 34 metal ions as a function of acetic acid concentration in the range 1–6 M. Results for two- and three-component separations by elution with 1 M acetic acid are given in order to illustrate the effectiveness and utility of the present method.
