Abstract
Eu(III) sorption on TiO2 (anatase) was investigated as functions of pH, ionic strength and Eu(III) concentration by using a batch experimental method. It was found that Eu(III) sorption on anatase is strongly pH-dependent, but insensitive to ionic strength. A constant capacitance model with three inner-sphere surface complexes, ≡SOEu2+, ≡SOEuOH+ and ≡SOEu(OH)3-, was used to interpret Eu(III) sorption on anatase in the absence and presence of carbonate (pCO2=10-3.58 atm).
