“…According to Guo et al (2023), a coordination interaction with the nitrogen/oxygen-containing groups of the functionalized zeolitic imidazole frameworks-functionalized resulted in efficient sequestration of lead and copper ions. Similarly, the exchange of ions within the zeolitic structure by the heavy metal cations was also reported during the adsorption of copper (Dasgupta et al 2021) and chromium ions (Huang et al 2022) onto zeolite. However, the mechanism of heavy metal adsorption onto zeolite is mainly via cation exchange within the zeolitic structure and silanol groups-assisted electrostatic interactions.…”

Access to drinkable water is becoming more and more challenging due to worldwide pollution and the cost of water treatments. Water and wastewater treatment by adsorption on solid materials is usually cheap and effective in removing contaminants, yet classical adsorbents are not sustainable because they are derived from fossil fuels, and they can induce secondary pollution. Therefore, biological sorbents made of modern biomass are increasingly studied as promising alternatives. Indeed, such biosorbents utilize biological waste that would otherwise pollute water systems, and they promote the circular economy. Here we review biosorbents, magnetic sorbents, and other cost-effective sorbents with emphasis on preparation methods, adsorbents types, adsorption mechanisms, and regeneration of spent adsorbents. Biosorbents are prepared from a wide range of materials, including wood, bacteria, algae, herbaceous materials, agricultural waste, and animal waste. Commonly removed contaminants comprise dyes, heavy metals, radionuclides, pharmaceuticals, and personal care products. Preparation methods include coprecipitation, thermal decomposition, microwave irradiation, chemical reduction, micro-emulsion, and arc discharge. Adsorbents can be classified into activated carbon, biochar, lignocellulosic waste, clays, zeolites, peat, and humic soils. We detail adsorption isotherms and kinetics. Regeneration methods comprise thermal and chemical regeneration and supercritical fluid desorption. We also discuss exhausted adsorbent management and disposal. We found that agro-waste biosorbents can remove up to 68–100% of dyes, while wooden, herbaceous, bacterial, and marine-based biosorbents can remove up to 55–99% of heavy metals. Animal waste-based biosorbents can remove 1–99% of heavy metals. The average removal efficiency of modified biosorbents is around 90–95%, but some treatments, such as cross-linked beads, may negatively affect their efficiency.

“…Batch mode or discontinuous adsorption experiments for basic adsorbent characterisation (system equilibrium setup and adsorption isotherm calculations) were carried out according to the conventional method reported elsewhere [10][11][12][21][22][23][24][25][26][27], as follows: A 30 mL of solution, measured with analytical precision, of different initial concentrations, together with 0.3 g of adsorbent, weighed to 4 decimal places, were added into resealable plastic vials and mixed using rotation mode for the selected time at constant speed (180 rpm) on a Biosan SIA Multi-rotator in order to reach equilibrium. The aqueous solutions obtained through a 0.45 µm cellulose membrane filtration were analysed.…”

“…Among the recommended techniques like chemical precipitation, ion exchange, membrane filtration, coagulation-flocculation and adsorption, adsorption is undoubtedly one of the most economically viable and effective methods in water technology [8][9][10][11][12][13][14][15]. Adsorption is also considered one of the most suitable methods for final water purification, owing to its simplicity and the availability of various natural or commercial adsorption materials [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Over the last decade, nanomaterials-based zeolite-type mesoporous adsorbents have garnered attention in the scientific community for removing hazardous metal pollutants, including radionuclides.…”

“…Over the last decade, nanomaterials-based zeolite-type mesoporous adsorbents have garnered attention in the scientific community for removing hazardous metal pollutants, including radionuclides. Their improved adsorption ability and selectivity are based mainly on the organic ligand complexation with target ions [23][24][25][26][27]31,32]. In the case of an ion exchange separation of Cs, inorganic ion exchangers are found to be superior over organic ion exchangers due to their thermal stability, resistance to ionising radiation and good compatibility with final waste forms.…”

This study investigates the adsorption of selected water pollutants, namely caesium and copper, by using natural zeolite of the clinoptilolite type, as well as clinoptilolites coated with MnOx, FeO(OH)-MnOx and FeO(OH). A comprehensive evaluation of these processes was conducted. The kinetics of Cs and Cu adsorption on all examined samples smoothly followed the pseudo-second-order kinetic model, with the liquid film step regarded as the slower step in both cases. The Langmuir isotherm model provided the most accurate description of Cs and Cu adsorption for all examined samples. However, when considering natural clinoptilolite and FeO(OH)-clinoptilolite systems in relation to Cu(II), the Redlich–Peterson model slightly outperformed the Langmuir model. The modification of clinoptilolite with Mn and Fe oxyhydroxides did not significantly enhance the removal efficiency of Cs compared to the unmodified sample. In contrast, the adsorption capacity, especially for MnOx-clinoptilolite, increased fourfold for Cu and other tested cations such as Pb and Zn, indicating improved efficiency in these cases.

“…The term "green adsorbent" refers to materials derived from agricultural waste, natural sources, etc., that are low-cost, abundant, and environmentally benign, suitable for adsorption (Kainth et al, 2024). Studies have reported the use of clay minerals (Denis et al, 2010;Dasgupta et al, 2021), biomass waste (El Nemr et al, 2020;Mancilla et al, 2022), activated carbon (Yüksel and Orhan, 2019;Sharififard et al, 2021;Pereira et al, 2024) for the removal of contaminants from water. Clay materials are considered highly promising and cost-effective adsorbents (Esmaeili et al, 2019;Khan et al, 2023).…”

The removal of hazardous metal ions from polluted water is a crucial process aimed at enhancing water quality. In this study, we conducted a dynamic adsorption investigation utilizing natural green clay for the removal of hexavalent chromium from aqueous solutions. The material underwent characterization through various techniques, including fluorescence spectrometry (XRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and nitrogen-physisorption (BET). Column tests of green clay material and sand mixtures were performed to evaluate sorption in dynamic systems. Adsorption conditions were examined by varying the initial Cr6+ concentration, flow rate and column height. The maximum purification was achieved at a concentration of 50 mg/L, a flow rate of 3mL/min and a bed height of 12 cm. The mathematical models of Bohart-Adams, Thomas, and Yoon-Nelson were employed to analyze experimental data and predict breakthrough curves in continuous adsorption. Through comparison of R2 values, it was determined that the Yoon-Nelson and Thomas diffusion models effectively capture and accurately describe the experimental data. The results obtained indicate a potential expansion of fixed-bed adsorption for the heavy metals treatment in industrial-scale wastewater. Additionally, the natural green clay material exhibited remarkable reusability and showed promising characteristics for various environmental and industrial applications.
