A comparative study of kinetic models for ligand exchange of I 0 r Cl 0 and Br 0 r Cl 0 as ligands as a function of pH and concentration using diaminoethylsporopollenin (DAE-sporopollenin) resin were investigated during the ligand-exchange reaction of the liquid phase. A batch technique was employed

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
The specific rate coefficients and ligand sorption isotherms of Br and I- as ligands on diaminoethyl-sporopollenin were determined as a function of pH and temperature between 20 and 60Β°C. The ligand exchange rates were measured just after the rapid mixing of the ligand solution with the resin suspen
