نبذة مختصرة : Layered double hydroxides (LDHs), also known as hydrotalcite-like compounds (HTs), comprise a special group of layered materials. Their structure consists of positively charged layers of mixed divalent (MII) and trivalent (MIII) metal hydroxide [MII1-xMIIIx(OH)2]x+, with the positive charge being balanced by inorganic hydrated anions (An-x/nmH2O), which occupy the interlayer space. LDHs have anion exchange properties and, therefore, are good sorbents for anionic pollutants. In addition, the anionic exchange properties of LDHs allow the intercalation of organic anions in the interlayer space to render the LDH surface hydrophobic. This increases its affinity to hydrophobic organic compounds ; MINECO Project AGL2011-23779, FACCE-JPI Project Designchar4food, JA Research Group AGR-264 and FEDER-FSE (OP 2007-2013). ; Peer Reviewed
