Description
Separation of REE in the presence Zn2+3-ion by elution with 0.025 mol/l diethylenetriaminepentaacetic acid solution, containing 0.0155 mol/l of citric acid, on the cation exchanger KU-2 in H-form has been studied. It is shown that zinc is washed out by two zones. Zinc distribution in these zones depending on parameters of chromatographic process influences the efficiency of REE separation. The mechanism of the process is suggested. 3 refs., 5 figs
