Fabrication of Cu-doped iron oxyhydroxide for phosphate removal: A comprehensive spectroscopic, equilibrium, and thermodynamic approach

“…The solid sample was characterized using a surface area analyzer, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), pHiep and Fourier transform infrared (FT-IR) spectroscopy. The results reveal that the surface area of iron oxyhydroxide increases from 35.1 m2/g to 126 m2/g with Cu ion doping, which may be due to the difference in ionic radii of Fe+3 (0.645 Å) vs. …”
