Arsenate adsorption on an Fe-Ce bimetal oxide adsorbent: Role of surface properties
TL;DR: An Fe-Ce bimetal adsorbent was investigated with X-ray powder diffraction, transmission electron micrograph, Fourier transform infrared spectra, andXPS methods for a better understanding of the effect of surface properties on arsenate (As(V), proving that the adsorption of As(V) by Fe- CeO8 is mainly realized through the mechanism of quantitative ligand exchange.
