Resumo
The secure disposal of radioactive wastewater, a waste from nuclear operations,
presents a significant challenge due to the presence of hazardous radionuclides like
cesium. The efficient removal of cesium, a major fission product with a long half-life and
potent radiation, is crucial for environmental and human health protection. Zeolites, with
their high ion exchange capacity and porous structure, offer a promising solution for
cesium removal from wastewater. The potential to synthesize zeolites from abundant and
cost-effective agro-industrial residues further enhances their appeal for sustainable
wastewater treatment. The present study investigates the adsorption of cesium from
simulated radioactive wastewater using zeolite type A synthesized from sugarcane bagasse
ash, a readily available Brazilian byproduct. The synthesized zeolite was characterized by
X-ray fluorescence spectroscopy, X-ray diffraction, and thermal analysis techniques. The
results confirmed the successful synthesis of high-purity zeolite A with excellent
adsorption capacity for cesium. The structural integrity and thermal stability of the zeolite
were maintained even after cesium adsorption, making it suitable for immobilization
processes. The findings highlight the potential of zeolite synthesized from sugarcane
bagasse ash as an effective and sustainable material for the treatment and removal of
cesium from radioactive wastewater, contributing to environmental remediation efforts
in the nuclear industry.
