“…Many conventional water treatment methods have been incorporated to treat water contaminated with heavy metals and radioisotopes such as solvent extraction, sorption, and ion exchange (El-Sadek et al 2021 ; Hassan et al 2019 ; Mahrous et al 2022 ; Mansy et al 2023 , 2017 ). There are some studies about the influence of conventional treatments applied at water treatment plants to reduce radioactivity (Arnal et al 2000 ; Baeza et al 2006 ; Commission 2002 ; Gäfvert et al 2002 ; Jiménez and De La Montaña, 2002 ; Montaña et al 2013 ; Munter 2013 ; Palomo et al 2010 ). However, these methods have several limiting factors including thermal instability, the formation of toxic intermediates, and high energy consumption (Clearfield 2010 ; Dakroury et al 2020 ; Wang and Zhuang 2019 ).…”

“…However, these methods have several limiting factors including thermal instability, the formation of toxic intermediates, and high energy consumption (Clearfield 2010 ; Dakroury et al 2020 ; Wang and Zhuang 2019 ). A promising use for membrane technology is the efficient removal of heavy metals and radioactive pollutants from aqueous solutions (Arnal et al 2000 ; Zakrzewska-Trznadel 2013 ; Dakroury et al 2020 ; Kumar et al 2020 ). The advantages of using membrane technology for radionuclide removal include a high decontamination factor (or volume reduction), low energy consumption, and compatibility with existing systems.…”

Cesium removal from aqueous solutions of radioactive waste streams is a challenge in the field of radioactive waste management; this is due to the small atomic radii of Cs+ metal ions and their high migration ability. So, the development of a withstand system for the removal of Cs+ is crucial. In the current study, the removal of radioactive cesium from aqueous solutions using an RO-TLC membrane was studied. Two modifications were conducted; the first is to enlarge the cesium metal ion radii by interacting with mono- and dibasic acids, namely, stearic acid, tartaric acid, citric acid, and EDTA, and the second is the modification of the RO membrane pore size via reaction with the same acids. The modification was confirmed using SEM, FTIR, and EDX analysis techniques. The Cs+ and K+ rejection capacities and water permeability across the membrane at 1.5 bars were evaluated. Along with using the above-mentioned acids, the Cs+ metal ion retention index (RCs) was also obtained. It was found that employing EDTA as a chelating agent in an amount of 1.5 g/L in conjunction with the variation of feed content since it provided the highest value of RCs ~ 98% when used. Moreover, the elution of Cs+ using water, EDTA, ammonia, and HCl is also investigated. The optimal value of the eluent concentration was (0.25 M) HCl. Finally, Langmuir and Freundlich isotherm models were applied for a better understanding of the sorption process. The results of the present work more closely match the Langmuir isotherm model to determine the dominance of the chemical sorption mechanism.
