摘要: Abstract Adsorption of europium on manganese dioxide from nitric and perchloric acid solutions has been studied as a function shaking time, concentration electrolytes, adsorbent, adsorbate. The influence different anions cations adsorption examined. other metal ions the oxide measured, under specified conditions, to check its selectivity. decreases with an increase in electrolyte or own concentration. Zr(IV), Cr(III), La(III), Ce(III), EDTA, citrate reduce appreciably both acids. More than 99% adsorbed column can be eluted 40 cm3 3 mol/dm3 solution. Europium obeys Freundlich isotherm media over concentrations ranging 10−7 10−4 g/cm3
