In this work the application of natural montmorillonitetype clays (Mt-Na) activated by specificfunctionalizing agents is studied. Objective. Activate a Mt-Na type clay and use it in the bleaching process of crude palm oil, and for the removal of the indigo carmine dye used in the textile industry.Materials and methods. The clay was provided by the companyBentominercol S.A.S. (Líbano-Tolima). Crude palm oil was purchased from the Oleodavilapalm plant in the Tumaco region (Nariño).The chemical reagents used are of analyticalgrade. The modified clay was characterizedby X-rays, TGA thermal analysis, and FTIR infrared spectroscopy.Results. The bleachingof crude palm oil was achieved, obtaining a CB bleaching capacity of 96%. It was also used in the adsorption of the indigo carmine dye in a prepared water matrix contaminated with said dye, where the removal of up to 97% of said dye in water was achieved.Conclusions. Montmorillonite clays are a material that is easily modified or structurally functionalized,which allows obtaining new materials for technical and industrial application accordingto the results obtained in this study.esAcceso abiertoCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráArcillaCompuestos químicosAdsorciónAceite de palmaAceites vegetalesinfo:eu-repo/semantics/openAcces
