dc.description.notes | Summary: AbstractThe sorption efficiency ofOpuntia ficus indicacactus fibres regarding the removal of trivalent europium (Eu(III)) from aqueous solutions has been investigated prior and after the chemical treatment (phosphorylation and MnO2-coating) of the biomass. The removal efficiency has been studied as a function of pH, europium concentration, mass of the adsorbent, ionic strength, temperature and contact time. Evaluation of the experimental data shows that biosorption is strongly pH-depended and that the MnO2-coated product presents the highest sorption capacity followed by the non-treated and phosphorylated material. Results have been analysed by Langmuir, Freundlich and Dubinin–Radushkevich isotherms, and the Langmuir model is more suitable to describe the process. The sorption reactions are entropy-driven, and the kinetics follows a pseudo-first order rate expression, described by Lagergren. In addition, the results show that the fibres of theOpuntia ficus indicacactus possess significantly higher sorption capacity than other biomass by-products reported in literature and that the removal of europium from contaminated waters is expected to be more effective in the case of the chemically treated biomasses.</p> | en |
