Kinetic and thermodynamic sorption studies of Fe(iii) and Zr(iv) by DFO@Purolite, a desferrioxamine B based chelating resin

DFO@Purolite resin efficiently sorbs Fe( iii ) and Zr( iv ) above pH 1. The Gibbs–Donnan model enabled to determine the stoichiometry and stability of the complexes formed in the solid phase and to predict the sorption behaviour of the material.
