    Synthesis, characterization and acute aquatic toxicity of cerium oxide nanoparticles to freshwater green algae

  • Original language description

    The article describes the preparation of cerium oxide nanoparticles (nanoCeO2) via precipitation method from the selected default salt Ce(NO3)3.6H2O and its acute aquatic toxicity. The resulting nanoparticles were characterized by X-ray powder diffraction analysis, which showed the cerium oxide nanoparticles to be with the crystallite size of 58 nm. Morphology of the cerium oxide nanoparticles was examined by scanning electron microscopy, where agglomerates of spherical shaped nanoparticles were observed. The elemental composition of the product was confirmed by EDX analysis. Freshwater green algae (Desmodesmus subspicatus) served as a model organism for evaluation of acute aquatic toxicity. Effective concentration of toxicity EC50 was determined for the concentration 0,49 g.dm-3 of cerium oxide nanoparticles to freshwater green algae Desmodesmus subspicatus.
