Description
Summary:The experimental data are presented on the purification of Am, Cm from Pu and Fe by anion-exchange chromatography with the Bio-Rad AG1-X8 sorbent (50–100 mesh) as well as data on the separation of Am, Cm, and Cf by ion-exchange chromatography with Bio-Rad AG50W-X8 cation exchange resin (200–400 mesh) in the NH 4 + form. Sorption was carried out from a solution of 0.1 M HNO 3 , followed by elution with a solution of the ammonium salt of α-hydroxyisobutyric acid (hereinafter α-HIBA) with pH 5.0. The α-HIBA ammonium salt concentration was varied within 0.1–0.2 M. The best results were achieved with successive elution with α-HIBA ammonium salt solutions at concentrations of 0.1 and 0.15 M. The characteristics of the developed chromatographic process of cation exchange purification of Cm using an α-HIBA ammonium salt solution as an eluent were determined: the number of theoretical plates N , distribution coefficient D , selectivity (separation factor) α, and resolution R S .
