Treatment of actual radioactive wastewater containing Cs-137 using kaolinite clay minerals as eco-friendly adsorbents

The radionuclide radiation risks brought on by nuclear weapons cannot be disregarded by the operators. To protect the public's health, radioactive cesium (Cs) polluted water must be treated with sustainable materials. In this work, batch adsorption studies were investigated to separate the radioactive isotope Cs-137 from the actual radioactive wastewater. In a batch adsorption method, the natural clay kaolinite was described and chosen as an adsorbent. After 2 h, equilibrium was attained with kaolinite having a removal efficiency of 75% for Cs-137. The adsorption kinetics of Cs-137 on the surfaces of kaolinite clay were assessed. The experimental kinetic data for kaolinite generated an outstanding match with the pseudo-first-order kinetic model. As a result, kaolinite was determined as the appropriate media to be adsorbent for Cs-137.
