Uranium Removal From Nitrate Solution by Cation Exchange Resin (Amberlite Ir 120), Adsorption and Kinetic Characteristics

Abstract

The present work aims to study the adsorption behavior of uranium ions from nitrate solutions using the strong acid cation exchange Amberlite IR120 resin. Batch shaking sorption experiments are carried out to evaluate the performance of the studied resin in the uranium adsorption. The adsorption parameters including contact time, pH, initial uranium concentration and temperature have been optimized. The physical parameters including the adsorption kinetics, the isotherm models and the thermodynamic data have also been determined to describe the nature of the uranium adsorption by the investigated resin. The modellated data has been found to agree with both the exothermic pseudo first order reaction and the Langmuir isotherm. The applied procedure was used for uranium ions removal from scrub and raffinate liquors.
