The sorption of anionic ligands such as I 0 , Br 0 , and SCN 0 onto diaminoethyl-sporopollenin (DAE-sporopollenin) was investigated in both column and batch experiments at room temperature. The isotherm binding constants suggest that the resin is most efficient at the binding of I 0 compared with Br 0 or SCN 0 . The general ligand sorption affinity series observed was I 0 ú Br 0 ú SCN 0 . This ligand sorption could be described by considering the hydration of ions in the exchanger. The sorption behavior of the ligand exchanger and the possibilities of selectively removing and recovering ligands are discussed on the basis of their chemical and complexing properties.
