Removal of Uranium from Effluent Acidic Solution Using Manganese Oxide Coated Modified Talc (MOCMT)

Abstract

In this study, the unique manganese dioxide coated modified talc (MOCMT) adsorbent was easily synthetic. (MOCMT) was evaluated as an adsorbent for the removal of U (VI) from effluent (=10 ppm) solution. To fit the adsorption results, the Langmuir and Freundlich isotherm models were applied, as well as the kinetic parameters of the adsorption process, which were measured and fitted. Five adsorption/desorption cycles with 0.3 M H2SO4 as an eluent were performed to test the reusability. The MOCMT was used to extract uranium from effluent solution produced after a four-cycle leaching/adsorption during the uranium milling process in the Gattar project.
