Cerium oxide nanoparticles for color removal of indigo carmine and methylene blue solutions. Thus, CeO 2 NPs may be suitable for removal of anionic dye effluents at room temperature.Ĭitation: Álvaro Guzmán Aponte, María A Llano Ramírez, Yuliana Cadavid Mora, Juan F Santa Marín, Robison Buitrago Sierra. The experimental results showed that the highest color removal was obtained for indigo carmine (≈ 90% at pH 2.5 within 180 min). ![]() The surface chemical analysis of CeO 2 NPs was performed by using an X-ray photoelectron spectroscopy (XPS), and the presence of functional groups and the absorption spectra in CeO 2 NPs were investigated by Fourier-transform infrared spectroscopy (FTIR) and by UV-vis spectroscopy, respectively. In addition, the morphology was studied by using Scanning Electron Microscopy (SEM) and a semi-spherical morphology was observed. The structural properties and crystallinity of NPs were determined by X-ray diffraction (XRD) and a cubic phase of ceria with 13.5 nm crystallite size was confirmed. In this work, CeO 2 nanoparticles (NPs) were synthesized by sol-gel method, characterized and used for color removal of indigo carmine and methylene blue dye solutions under visible light.
