Abstract
There is a considerable interest in the study of lamellar compounds that present anionic exchange capacity, like layered double hydroxides (LDHs) or layered hydroxy double salts (HDSs). Both of these classes of compound present structures similar to that of brucite. The HDLs can be represented by the general formula [MII(1-x) MIII(x)](OH)2Am-(x/m) . nH2O where MII represent a divalent cat…
