| description | In this work, the removal of the radioactive element Cs-137 from actual radioactive wastewater was studied by batch adsorption studies. To lower the dangers of radioactive contamination, bentonite, a naturally occurring clay mineral, was used as an adsorbent. The bentonite clay mineral was characterized using chemical composition analyses, (XRD), (SEM), (EDX), (BET) surface area analysis, and (FT-IR). Experiments of batch adsorption were conducted to determine the optimal adsorbent. After two hours, equilibrium was attained with a bentonite Cs-137 removal effectiveness of 98%. The kinetics of Cs-137 adsorption on the bentonite clay surfaces was investigated. A good match was obtained for the bentonite kinetic data using the pseudo 2nd order kinetic model. As a result, it was found that bentonite was the good medium for adsorption. The findings provide helpful details on the ways in which bentonite clays adsorb radioactive Cs-137 and remediate pollution. The chosen of bentonite clay adsorbents was displayed to be hopeful adsorbent for the adsorption of the radioactive Cs-137 isotope because of effective material, very cheap, and available. |
