| Abstract: | 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 CO32- retention. Carbonate phobic character was observed and it may be correlated to 3 the poor basicity of hydrotalcites, thus, to the electronegativity of M2+ cations. (c) 2007 Elsevier Masson SAS.
