Mercedes Regadío is a postdoctoral fellow in the Department of Chemistry at KU Leuven (Catholic University of Leuven). Between 2007-13, Mercedes studied the sorption of contaminants in landfill leachates through clayey substrata, in the Department of Geology and Geochemistry of the Autonomous University of Madrid (UAM). She has extensive experience in the characterization of soil and water, the determination of physicochemical processes in pollutants-soil-water interactions and in the description of the fate, transport and biogeochemistry of pollutants.

In 2014, Mercedes joined KU Leuven and she is currently working on the recovery of metals by ion exchange resins and solvent extraction. Her interests range from the attenuation of metals in natural soils to immobilize them, to sorption and separation of metals to concentrate them and recover them with a three-fold objective: the supply of critical metals, the recycling of industrial waste and the remediation of soils.

Present research lines

  1. Recovery and reuse of scandium from bauxite residue (red mud)
  2. Recycling technologies of rare earths elements (critical metals)
