The potential for remediation by adsorption of SCN on ferrihydrite, the influence of sulfate
(SO42) on SCN adsorption, and the fate of adsorbed SCN during ferrihydrite aging were studied
using macroscopic techniques complemented with attenuated total reflectance–Fourier transform infrared
analysis (ATR–FTIR), X-ray powder diffraction (XRD) and transmission electron microscopy (TEM).
