“…At the K + concentration of 50 mg/L, the Cs + sorption value decreases by a factor of almost 1.5, and at the concentration of 250 mg/L the K + ions practically suppress the sorption, which additionally confirms the ion-exchange mechanism of the Cs + sorption, taking into account the close radii of the hydrated potassium and cesium ions [33]. Considering low concentration values of K, Na, and Ca in the tested lake water of this study (Table 2), it could be hardly probable that these cations affected the 137 Cs sorption/desorption processes.…”

“…, and Mg 2+ as typical components characteristic of natural waters have a competing effect on the sorption/removal of cesium radionuclides from aquatic media [33]. It can be assumed that dissolved potassium and ammonium would compete with cesium for adsorption sites, thereby decrease K d values.…”

“…Considering low concentration values of K, Na, and Ca in the tested lake water of this study (Table 2), it could be hardly probable that these cations affected the 137 Cs sorption/desorption processes. However, it could be taken into account that large hydrated cations, such as Na + , Ca 2+ , and Mg 2+ , tend to pry the layers of sorbents further apart, whereas small hydrated cations, such as K + , have the opposite effect [33]. Pu and sorption capacity of environmental-friendly and synthetic sorbents from lake water spiked with 236 Pu (pH 6), using the dynamic flow column method.…”

Investigations on the pre-concentration of radionuclides ( 137 Cs and plutonium isotopes) from fresh water on solid matrices are presented in this study. A particular focus was given to an innovative physico-chemical removal process such as adsorption of radionuclides from an aqueous medium on new type adsorbents, environmental-friendly materials. Sorption of the tested radionuclides from the lake water solution by environmental assays and synthetic sorbents was compared. Lake water was analyzed for main anions, micro-and macroelements, using ion and atomic absorption chromatography methods, respectively. Batch type and dynamic flow column laboratory experiments were performed. The sorption-desorption capacity of radionuclides by the tested sorbents was estimated based on the results of α-and γ-spectrometric measurements. According to the removal efficiency results, moss can be considered as the best sorbent for plutonium of the tested environmental-friendly sorbents, whereas the moss sorption capacity exceeded even that of the tested synthetic ones. The highest Cs and different plutonium sorption in the moss apparently indicates different binding properties of these radionuclides to the moss, therefore further investigations on this issue are foreseen.

“…Moreover, ion exchange was the main removal mechanism in the sorption of Iand TcO4onto Mg-Al-LDHs [82,83]. While intercalating Zn-Al-LDH with hexacyanoferrate (II) ions resulted in a maximum sorption capacity towards Cs(I) of 56.2 mg/g at pH 6.0 [84]. Several LDH-based sorbents; SiO2@LDH, Fe3O4@polydopamine@LDH, graphitic-C3N4@LDH, and polydopamine@LDH, were utilized for U(VI) removal from aqueous solutions, where they showed maximum sorption capacities at pH 5.0 and 25 o C (considering different sorbent dosage) of 303.1, 344.4, 99.7, and 142.9 mg/g, respectively [85][86][87][88].…”

In this study, mini review is presented on the use of different sorbents for radionuclides removal of from water. Four sorbents categories were considered: carbon-based, nanomaterials, bio-sorbents, and miscellaneous sorbents. Carbon-based sorbents showed excellent removal performance towards radionuclides, owing to the high specific surface area and abundant oxygen-containing functional groups. While Fe 0 and Fe 0 -based composites was found to exhibit rapid sorption rate, high removal capacity, and strong redox performance for radionuclides, indicating that such nanomaterials can be very promising for in-situ removal of radionuclides, once their drawbacks (aggregation and poor mobility) are overcome. The use of bio-sorbents showed high potential of such materials to remediate radioactive contaminated water under specific environmental conditions. The critical review in this study shall represent a great contribution to the potential researchers and decision makers choosing the highly efficient, feasible, and environmentally friendly sorbents for the removal of radionuclides from aqueous solutions.

“…Concerning cesium adsorption in wastewater, a study was carried out by Pshinko et al (2015) in order to develop a LDH containing Al and Zn, sandwiched with hexacyanoferrate(II) (LDH-FeCN) [114]. This material shows excellent cesium selectivity and removes 99.8% of this radionuclide from wastewater.…”

The energy industry (nuclear, battery, mining industries, etc.) produces a large quantity of hazardous effluents that may contain radionuclides (137Cs and 90Sr in particular) and heavy metals. One of the hardest tasks of environmental safety and sustainable development is the purification of wastewater holding these pollutants. Adsorption is one of the most powerful methods for extracting toxic compounds from wastewater. This study reviews the usefulness of clay minerals as adsorbent for removing these hazardous elements to clean up energy production processes. Phyllosilicates are able to extract several heavy metals from effluent, as widely examined. A particular focus is given to synthetic phyllosilicates and their abilities to entrap heavy metals with a special attention paid to those synthesized by sol-gel route. Indeed, this method is attractive since it allows the development of organic–inorganic hybrids from organosilanes presenting various functions (amino, thiol, etc.) that can interact with pollutants. Regarding these pollutants, a part of this review focuses on the interaction of lamellar materials (natural and synthetic phyllosilicates as well as layered double hydroxide) with heavy metals and another part deals with the adsorption of specific radionuclides, cesium and strontium.
