Metal-sulfide/Polysulfide Functionalized Layered Double Hydroxides – Recent Progress in the Removal of Heavy Metal Ions and Oxoanionic Species from Aqueous Solutions

This review summarizes various syntheses and structural characterization of metal sulfide/polysulfide intercalated LDHs and their sorption properties with mechanisms for various chemically toxic inorganic species (heavy metal cations and oxo-anions).
