Resumen:

Low dimension cation Exchange materials, Duch as layered silicates, have been more extensively studied than their anion counterparts. Actually, hydrotalcite-like compounds are almost the single anionic exchange materials widely studied so far. However, in recent years, Ni,Zn layered double hydroxyacetates (LDA) have been also tested as anions exchangers. The structure of these materials can be described as derived from brucite-like Ni(OH)2, where up to 25 % of Ni2+ cations have been removed from the octahedral holes, and substituted by Zn2+ cations  which are located outside the layers, coordinated to three hydroxyl groups, and completing a tetrahedral coordination with water molecules and/or interlayer acetate anions. Following previous studies with hydrotalcite-like materials, we here report on intercalation of vanadate in Ni,Zn LDA.
