Abstract

Removing the hazardous and unstable radioactive isotopes has been considered an arduous task, though they are in minimal concentrations. Cesium-137 ( 137 Cs + ) is a primary fission product produced by nuclear processes. Even at low concentrations, such radioactive material is a menacing source of contaminants for the environment. The current study aims to separate 137 Cs + from a real contaminated aqueous solution via an ion exchange mechanism using ammonium molybdophosphate–polyacrylonitrile (AMP-PAN) resin loaded in an extraction chromatographic column that possesses considerable selectivity toward cesium ion (Cs + ) due to the specific ion exchange between 137 Cs + and NH 4+ . Additionally, the proposed interaction mechanism between 137 Cs + with APM-PAN resin has been illustrated in this study. The results disclosed that the optimum efficient removal of 137 Cs + (91.188%) was obtained by the AMP-PAN resin using 2 g·L −1 , while the distribution adsorption coefficient (129.359 mL·g −1 ) was at pH 6. The isothermal adsorption process was testified through the Langmuir and Freundlich models. The estimated maximum adsorption capacity reached 140.81 ± 21.3 mg·g −1 for the Freundlich isotherm adsorption model. Finally, AMP-PAN resin could eliminate 137 Cs + from water effectively through adsorption.
