Molecular insight into the mode-of-action of phosphonate monolayers as active functions of hybrid metal oxide adsorbents. Case study in sequestration of rare earth elements

Abstract

Organic–inorganic hybrid adsorbents for separation of rare earth elements were prepared by grafting of amino phosphonic acid ligands onto mesoporous TiO₂. Their structure and capacity were elucidated using X-ray studies of molecular model compounds.
