The adsorption of europium on manganese dioxide from a binary mixture of aqueous sulfuric acid and methanol has been studied in relation to the concentration of adsorbate. The influence of contact time, composition of binary mixture, and foreign ions was also investigated. Citrate, chromate, molybdate, EDTA, Cr(III), Fe(III), and Al(III) drastically reduce adsorption. Adsorption of other metal ions under the same conditions was also investigated. Based on the observed data, separation of europium from mercury can be achieved.
