Adsorption of europium on manganese dioxide from nitric and perchloric acid solutions has been studied as a function of shaking time, concentration of electrolytes, adsorbent, and adsorbate. The influence of different anions and cations on adsorption has been examined. The adsorption of other metal ions on the oxide has been measured, under specified conditions, to check its selectivity. Adsorption of europium decreases with an increase in electrolyte or its own concentration. Zr(IV), Cr(III), La(III), Ce(III), EDTA, and citrate reduce adsorption appreciably in both acids. More than 99% europium adsorbed on the oxide column can be eluted with 40 cm/sup 3/ of 3 mol/dm/sup 3/ nitric acid solution. Europium obeys the Freundlich adsorption isotherm in both media over concentrations ranging from 10/sup -7/ to 10/sup -4/ g/cm/sup 3/. 24 references, 7 figures, 3 tables.
