Resumo
The pseudoboehmite is a hydrated aluminum oxihydroxid produced by sol gel process started by inorganic precursor
as an inorganic polymerization system [1]. Several studies were done about pesudoboehmite, reaching its utilization
as an alumina precursor [2], drug delivery systems [3] (for drug like atenolol, acyclovir and glucantime for example) or
as a reinforcement agent to synthesis of polymeric matrix nanocomposites [4]. The intent of this work is contribute to
the study of the environment influence at pseudoboehmite nanoparticles. The nanoparticles were obtained by sol-gel
process, starting from aluminum nitrate and ammonium hydroxide solutions. The product of synthesis reaction were
characterized by Scanning Electron Microscopy (SEM), X-Ray Florescence (XRF), X-Ray Diffraction (XRD), Raman
Spectroscopy, specific weight, granulometry average and nitrogen adsorption (BET) analysis, identifying the
characteristics of the produced material and eventual adsorbed materials and respective effect on its properties. After
the characterization, were verified that the pseudoboehmite nanoparticles adsorbed other chemical agents as iron,
potassium, chrome and others.
