Hydrophilic olive cake extracts: Characterization by physicochemical properties and Cu(II) complexation
Kolokassidou, K.; Szymczak, W.; Wolf, M.; Obermeier, C.; Buckau, G.; Pashalidis, Ioannis (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 ...

Sorption of Cu(II) and Eu(III) ions from aqueous solution by olive cake
Konstantinou, M.; Kolokassidou, K.; Pashalidis, Ioannis (2007)The sorption of Cu(II) on olive cake, a biomass by-product of olive oil production, has been investigated by potentiometry at pH 6, I=0.1 M NaClO 4, 25∈°C and under atmospheric conditions. Numerical analysis of the ...

Studies on the interaction of olive cake and its hydrophylic extracts with polyvalent metal ions (Cu(II), Eu(III)) in aqueous solutions
Konstantinou, M.; Kolokassidou, K.; Pashalidis, Ioannis (2009)The paper presents and discusses the chemical affinity of two different forms of natural organic matter (e.g. in solid (SOM) and soluble form (DOM)) for Cu2+ and Eu3+ ions. In the this study SOM is represented by olive ...
