Laser-induced fluorescence spectroscopy was applied for the characterization of Eu(III) species sorbed on organic-inorganic hybrids such as montmorillonite coated with poly(acrylic acid) or poly(methacrylic acid) in aqueous solution (suspension)The emission lifetime and the emission spectra of Eu(III) sorbed on the organic inorganic hybrid indicated that Fu(III) can be sorbed as an Eu(III)polycarboxylate complex on montmorillonite The stabilities of the Eu(III)-polycarboxylate complex andinorganic Eu(III) species sorbed on montmorillonite control the species of Eu(III), i.e., organic or inorganic, sorbed on the organic inorganic hybrid. It was suggested that Eu(III) can be sorbed as a humate complex when an Eu(III) ion is contacted withan organic-inorganic hybrid, such as a humic acid-clay mineral hybrid, in a natural aquifer.
