Insight into the adsorption mechanisms of aqueous hexavalent chromium by EDTA intercalated layered double hydroxides: XRD, FTIR, XPS, and zeta potential studies

To understand the possible mechanisms of Cr(vi) adsorption on the surface of modified LDHs, we synthesized EDTA intercalated MgAl-LDH and its magnetic product, and evaluated their adsorption performance for Cr(vi) by batch experiments.
