Data for Fe(II)-Catalyzed Transformation of Pb/Cr sorbed Ferrihydrite

The data encompasses X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Fe/Cr K-edge X-ray Absorption Fine Structure (XAFS), solution chemistry insights, and acid treatment results for both pristine ferrihydrite (with and without Pb/Cr sorption) as well as ferrihydrite that has undergone reaction with dissolved Fe(II).
