“…6 . This pattern can be explained by the fact that when sorbent amounts rise, more active sites become available to adsorb more metal ions until equilibrium is achieved (El-Nagaar et al 2012 ; Mansy et al 2017 ; El-Din et al 2019 ; Hassan et al 2019 ; Abdel-Galil et al 2020 ; Abass et al 2022 ; Mahrous et al 2022a ). As a result, the optimal adsorbent dose for attaining the maximum percent removal is 0.05 g/5 mL.…”

“…The operation of nuclear power plants, reprocessing facilities, and research centers, as well as the utilization of radioisotopes in industry and medical diagnostics, all result in the generation of various radioactive wastes. The radioisotopes of strontium and cesium are classified as the most harmful isotopes produced in the nuclear industry due to their long half-life, high chemical activity, migration, toxicity, and relatively small atomic radii (Nasseh et al 2017 ; El-Din et al 2019 ; Mahrous et al 2022b ).…”

“…Inorganic materials that are naturally occurring or created synthetically have long been used as adsorbents for different radionuclides, primarily alkali and alkaline earth cations (Abdel-Galil et al 2018 ; Bediako et al 2020 ; Hai et al 2020 ). Due to their strong radiation resistance, thermal and mechanical stability, and compatibility with ultimate waste forms, it is suitable for radioactive waste disposal (Pandiarajan et al 2018 ; El-Din et al 2019 ; Akinhanmi et al 2020 ). Several synthesized inorganic sorbents have significant affinities for one or more radionuclides throughout a broad pH range.…”

The crystalline phase of molybdenum titanium tungsto-phosphate (MoTiWPO4) as an inorganic sorbent material was synthesized via the sol–gel method. The physicochemical characteristics of MoTiWPO4 were evaluated by using Fourier transform infrared (FT-IR), scanning electron microscope (SEM), energy dispersive X-ray (EDX), thermal analysis (TGA-DTA), and X-ray diffraction (XRD). MoTiWPO4 sorbent material exhibits a high chemical resistance to HNO3, HCl, and alkaline media. MoTiWPO4 has good thermal stability as it retained about 75.63% of its saturation capacity upon heating at 500 °C. The sorption studies for several metal ions revealed marked high sorption efficiency of MoTiWPO4 towards Cs+ and Sr2+ ions which reached 99% and 95%, respectively. The saturation capacity of MoTiWPO4 for Cs+ and Sr2+ is 113 and 109 mg/g, respectively. MoTiWPO4 is approved to be successfully eliminating both 137Cs and 85Sr from liquid radioactive waste streams by %eff. of 92.5 and 90.3, respectively, in the presence of competing ions from 60Co(divalent) and 152Eu (trivalent), confirming the batch experiment results for the removal of Cs+ and Sr2+ metal ions. Furthermore, the decontamination factor exceeds 13.3 in the case of 137Cs and 10.3 for 85Sr.

“…Adsorption capacity typically increases as adsorbent mass increases. More adsorption sites become available to attract and immobilize cesium ions when the amount of adsorbent material in contact with the cesium-containing solution rises, causing a more incredible amount of cesium ions to be taken from the water until all possible adsorption sites are saturated [9].…”

Metal ion contamination has been a public concern due to its negative impact on human health and the environment. Cesium (Cs), a harmful metal ion, can cause cell damage; acute radiation syndrome includes nausea, vomiting, diarrhea, bleeding, and, in extreme cases, death. As a result, removing cesium ion from water is critical. This research aims to examine the capacity of a novel adsorbent derived from paper industry solid waste to remove cesium ion from water. The adsorption process was carried out with some variables including adsorbent dose, solution of pH, contact time, initial Cs concentration, and adsorbent form. According to characterization data, paper industry sludge contains elements such as SiO2 (28.1%), CaO (21.8%), Al2O3 (16.1%), and Fe2O3 (12%), among others. The surface area of the adsorbent is 100 m2/g and a diameter of 3.8 nm. Following equilibrium, the current study discovered that the developed adsorbent has the highest cesium removal, up to 79% for 10 mg/L of Cs initial. The novel adsorbent has high adsorption removal and may be a promising adsorbent material for metal ion removal in water.

“…These low-cost locally available biomass/biomass wastes ensure the cost-effective manufacturing of activated carbon, and they also provide higher quality and enhanced adsorption performances [26]. Among biomass sources, rice husks [27], bamboo [28], sugarcane bagasse [29], potato peels [30], coconut shells [31], waste palm trunks [32][33][34] and mangrove woods [35][36][37] are rich in carbon content and hence can be used for the synthesis of activated carbon. These biomass sources are readily available in most countries, such as Bangladesh, and are also very effective for removing the concerned radionuclides.…”

A Critical Review of the Removal of Radionuclides from Wastewater Employing Activated Carbon as an Adsorbent

Radionuclide-contaminated water is carcinogenic and poses numerous severe health risks and environmental dangers. The activated carbon (AC)-based adsorption technique has great potential for treating radionuclide-contaminated water due to its simple design, high efficiency, wide pH range, quickness, low cost and environmental friendliness. This critical review first provides a brief overview of the concerned radionuclides with their associated health hazards as well as different removal techniques and their efficacy of removing them. Following this overview, this study summarizes the surface characteristics and adsorption capabilities of AC derived from different biomass precursors. It compares the adsorption performance of AC to other adsorbents, such as zeolite, graphene, carbon nano-tubes and metal–organic frameworks. Furthermore, this study highlights the different factors that influence the physical characteristics of AC and adsorption capacity, including contact time, solution pH, initial concentration of radionuclides, the initial dosage of the adsorbent, and adsorption temperature. The theoretical models of adsorption isotherm and kinetics, along with their fitting parameter values for AC/radionuclide pairs, are also reviewed. Finally, the modification procedures of pristine AC, factors determining AC characteristics and the impact of modifying agents on the adsorption ability of AC are elucidated in this study; therefore, further research and development can be promoted for designing a highly efficient and practical adsorption-based radionuclide removal system.
