Öğe Kinetic Study of Ligand Exchange Reaction of Anions as Ligands on DAE-sporopollenin(ACADEMIC PRESS INC JNL-COMP SUBSCRIPTIONS, 1996) Ersöz, M.; Vural, U. S.; Yiğitoğlu, M.; Sezgin, M.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 60 degrees C. The ligand exchange rates were measured just after the rapid mixing of the ligand solution with the resin suspension. The data have also been analyzed to obtain activation parameters Delta G, Delta H, and Delta S for reaction in the corresponding mixture. A single ligand-exchange process was observed; the sorption of ligand increased with decreasing pH and hydrated radius of ligands and increasing temperature. A reaction mechanism which describe the ligand exchange reaction is proposed.
