Abstract

The equilibrium and kinetic characteristics of the natural clinoptilolite from acidic medium have been determined. The adsorption parameters including pH, contact time, stirring rate and temperature have been optimized. The practical adsorption capacity of uranium upon the resin under the optimum conditions has been found to attain 5 mg/g which matches with Langmuir isotherm 4.48 mg/g. 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 natural clinoptilolite. The working natural clinoptilolite found to agree with both the pseudo second order reaction and the Langmuir isotherm. Scanning electron microscope (SEM), X-ray diffraction (XRD), and Thermogravimetric analysis (TGA) were used to examine the structure of the resulting adsorbent.
