Abstract

A series of hydrotalcite-type solids with different compositions containing aminoacids (D,L alanine and L-triptophan) between the cationic layers were prepared by the coprecipitation method at constant pH. In parallel two hydrotalcite samples containing (Ni and Al) and (Mg and Al) respectively, as reference samples, were prepared. The structure of the as synthesized solids was confirmed by X-Ray Diffraction and FTIR methods. The incorporation of the aminoacids during the synthesis in the interlayer anionic sheets was weighted by photocolorimetric analysis with ninhidrine. The lattice parameters values and the thermal behavior data show that the incorporation of the aminoacids in the hydrotalcite interlayers occured. The incorporation degree depends both on the aminoacid and the composition of solid..
