Adsorption of trivalent lanthanides by marine sediments
(2015)The interaction of Eu(III) with two different types of marine sediments has been investigated as a function of various parameters (e.g. pH, [Eu(III)]o, I, humic acid) to evaluate their effect on the Eu(III) adsorption. The ...

Competitive sorption of Cu(II) and Eu(III) ions on olive-cake carbon in aqueous solutions - A potentiometric study
(2010)The competitive sorption of Cu(II) and Eu(III) ions from aqueous solutions by olive-cake carbon, has been investigated by potentiometry at pH 6, I = 0.1 M NaClO4, 25°C and under normal atmospheric conditions. Evaluation ...

The effect of natural organic matter on the formation and solubility of M(OH)4 solid phases
(2014)In this study the formation of M(OH)4 solid phases (e.g. Th(IV), Ce(IV) and Zr(IV)) has been investigated as a function of the natural organic matter (NOM) concentration in 0.1 M NaClO4, in the pH range between 2 and 5, ...

Hydrophilic olive cake extracts: Characterization by physicochemical properties and Cu(II) complexation
(2009)Disposed olive cake generates hydrophilic components that can be mobilized in the aquatic environment. This paper deals with the characterization of such components, isolated by alkaline extraction. It is shown that these ...

Thermal stability of solid and aqueous solutions of humic acid
(2007)The effects of temperature on the stability of a soil humic acid were studied in the present work. Solid samples of Gohy-573 humic acid (HA) and dissolved ones in aqueous solution (pH 6.0, 0.1 mol L-1 NaClO4) were investigated ...
