Comparación metodológica de la determinación del contenido en agua en rocas salinas mediante titulación de Karl Fischer y termogravimetría

C. DE LAS CUEVAS

Abstract


Water rnay be present in geological formations, filling pores, as fluid inclusions or as hydrated minerals. This study shows a comparison different methodologies in the determination of the water content in rock salt subsamples, using Karl Fischer titration and thermogravimetry, in order to establish an efficient and routinary analytical methodology for water content determination. The study has shown significant discrepancies in the water content results for the same samples, depending on the methodology and the granulometry selected.
