Resumo: The use of natural clays from colombian mines in the analytes extraction for chromatographic analysis has opened a big window in the research of potentialities that those have in an other fields that yet has been studied, due to their excellent capacity of cationic exchange and their large physicochemical properties. In this paper has been studied the natural clays (sodium montmorillonite type MMT-Na) application intercalated by ionic liquids with different long carbon chain, showing that the new materials has been succesfully modified, this issue was corroborated by material charaterization through x-ray difraction (XRD), fourier transformed infrared (FTIR) spectroscopy, scanning electronic microscopy (SEM) and termogravimetric analysis (TGA). From other our studies with non-polar molecules for extraction process was delivered the intercalated clay MMT-Na by hexadecyl methyl imidazolium bromide ionic liquid [HexadMIM][Br] cause showed a better intercalation. This material has been put to the proof for ochratoxin A extraction through packed hollow fiber membrane developed by our group, given promisourious results to the future researchs in the development of new extraction techniques field by using new sorbent material
