摘要

This study investigated the sorption of europium on boehmite by batch method and explore the effects of solid–liquid ratio, pH, ionic strength and the addition of EDTA on sorption. Time-resolved fluorescence spectroscopy was employed to elucidate the sorption mechanism. The work found that under acidic conditions, the sorption of Eu(III) on boehmite surface is controlled by outer-sphere surface complexation, while under alkaline conditions, it shifts to inner-sphere surface complexation. Equimolar concentrations of EDTA only hinder the sorption in alkaline systems. Moreover, the higher concentration EDTA can reduce the sorption across the pH range.
