Resumen:
The synthesis method of three series of nitrated (Zn,Mn)-Al hydrotalcites in the presence of microwave irradiation is presented. MnO4 - anions were partially incorporated between the layers of those compounds and a staged intercalation occurred. In the presence of CO2, nitrated and permanganate intercalated hydrotalcites were tested in CO3 2- retention. Carbonate phobic character was observed and it may be correlated to the poor basicity of hydrotalcites, thus, to the electronegativity of M2+ cations. © 2007 Elsevier Masson SAS. All rights reserved.
