Characterized and cleaning process of montmorillonite clay from Parelhas, Rio Grande do Norte state, Brazil; Caracterizacao e processo de purificacao de argila montmorilonitica da cidade de Parelhas, RN, Brasil

Abstract

The application of montmorillonite nano composites has been improved in order to obtain dispersed phase with particles of nano metric dimensions. To obtain these nanoparticles, the clays must pass an effective purification process for removing unwanted materials, which would undermine the processes of intercalation and exfoliation of montmorillonite in a polymer matrix. This study intention to characterize and purify a montmorillonite clay from deposit recently discovered in the city of Parelhas in Rio Grande do Norte, through the separation of coarser materials by decantation followed by a chemical attack that promoted oxidation in samples where it was realized reduction of impurities such as organic matter and other substances that would hinder the achievement of nanoparticles. Under these conditions, the clay is suitable for the work as dispersed phase in a polymer matrix nano composite. The results were demonstrated by analysis of scanning electron microscopy (SEM), chemical analysis, BET and X-ray diffraction (XRD). (author)
