The aim of this study was to evaluate the removal capacity of metakaolin based inorganic polymers (IPs) for the removal of Rare Earth Elements (REEs) from aqueous solutions, namely scandium (Sc) and neodymium (Nd). Analytical techniques involving XRD, FTIR and SEM/EDS were used for the characterization and morphology analysis of the produced metakaolin IPs. Kinetic and equilibrium experiments were performed and the results were evaluated. Kinetic models of pseudo-first and pseudo-second order Lagergren were applied, while at equilibrium the isotherm models of Langmuir and Freundlich were studied.
