LDH materials are based on a metallic M2+/M3+hydroxide layered network. The interlayer space is occupied by anions to balance the intralayer positive charge therefore being anion exchangers. Such property allows inserting anionic species giving rise for instance to heavy metal removers1. To best accomplish this task the layered structure must display high surface area, crystallinity and low carbonate content (for the ease of ion exchange).Starting from a LDH Mg:Al whose synthesis was already optimized by a previous study, this material was submittedto hydrothermaltreatment at 80oCunderN2 atmosphere. Theanionic species inserted were tartrateion and EDTA (ethylenediamine tetraacetic acid)at pH=7. It was used a 22factorial design for the process optimization. The varied parameters were those of Table 1. Samples were characterizedby X-Rays Diffraction (XRD),Fourier-transform infrared spectroscopy (FTIR)andThermogravimetric analysis (TGA). The outcomes to be evaluatedwere the presence of EDTA or tartrate bands in FTIR spectra; dislocation of 003 peak in XRD patterns; and mass loss % relative to intercalated organic anions by TGA.Intercalation experimentsrevealed that EDTA leadedthe LDH’s layerstowards collapsesince low yields of the final material were achieved (~10%).However the tartrate insertion was effected in all experiments accordingtoFTIR resultsthat evidenced COO stretching mode at 1585 cm-1.TGA curves pointed to the highest mass loss of 54% relative to the set of intercalation conditions of 6h and 253 K. Therefore these were considered the best conditions for tartrate intercalation.XRD patterns of these samples are still in progress.
