“…The authors found that the highest sorption capability was up to 131.58 mg/g, with an adsorption rate greater than 95%. Their results suggest that montmorillonite clay could be effectively used as an adsorbent for various heavy metals from water and aqueous medium (Elsherbiny et al, 2018 ). Malima et al ( 2021 ) utilized the physically (thermal treatment at 300 ℃) activated Malangali kaolin clay (TAMK) to eliminate CO(II) and Cd(II) ions from artificially polluted water utilizing batch adsorption process.…”

In the present era of significant industrial development, the presence and dispersal of countless water contaminants in water bodies worldwide have rendered them unsuitable for various forms of life. Recently, the awareness of environmental sustainability for wastewater treatment has increased rapidly in quest of meeting the global water demand. Despite numerous conventional adsorbents on deck, exploring low-cost and efficient adsorbents is interesting. Clays and clays-based geopolymers are intensively used as natural, alternative, and promising adsorbents to meet the goals for combating climate change and providing low carbon, heat, and power. In this narrative work, the present review highlights the persistence of some inorganic/organic water pollutants in aquatic bodies. Moreover, it comprehensively summarizes the advancement in the strategies associated with synthesizing clays and their based geopolymers, characterization techniques, and applications in water treatment. Furthermore, the critical challenges, opportunities, and future prospective regarding the circular economy are additionally outlined. This review expounded on the ongoing research studies for leveraging these eco-friendly materials to address water decontamination. The adsorption mechanisms of clays-based geopolymers are successfully presented. Therefore, the present review is believed to deepen insights into wastewater treatment using clays and clays-based geopolymers as a groundbreaking aspect in accord with the waste-to-wealth concept toward broader sustainable development goals.

“…Compared with natural MMT, its maximum adsorption capacity is increased (Liu et al, 2016). Elsherbiny et al (2017) modified MMT by polyaspartate to prepare composite material polyaspartic acid-montmorillonite (IPS) to adsorb Cd(II) in water. The adsorption capacity of the composite material for Cd(II) is 67.57 mg/g, which is 29.84% higher than the adsorption capacity of Na-MMT before modification.…”

“…The adsorption capacity of the composite material for Cd(II) is 67.57 mg/g, which is 29.84% higher than the adsorption capacity of Na-MMT before modification. The thermodynamic parameters indicate that the heavy metal ion adsorption process is a spontaneous exothermic process (Elsherbiny et al, 2017). Yan et al (2019) introduced extracellular polymer (EPS) loaded on MMT to prepare EPS-MMT to adsorb Cd(II), and changed the mass ratio of EPS to MMT to obtain the maximum adsorption capacity.…”

Heavy metal pollution in water environment has always been a hot issue in environmental pollution research. Among various removal methods of heavy metal pollution, adsorption has attracted attention because of its low cost and low secondary pollution. Montmorillonite is one of an ideal adsorption materials because of its natural pore structure and a high specific surface area. In this review, the modification methods of montmorillonite are introduced. The adsorption effect of different heavy metal ions and the main factors affecting the adsorption are discussed in detail. Meanwhile, the adsorption mechanism is intensively reviewed. The removal of Cr(VI), Cd(II), Pb(II), Cu(II), Cs(I), Co(II), Hg(II), Zn(II), Ni(II), and other nine heavy metal ions by modified montmorillonite was summarized and discussed, and the optimal pH values for different adsorbents were also different, but they were all less than 7, and the removal rates of heavy metal ions by modified montmorillonite under optimal conditions were all greater than 90%. It is concluded that the composite montmorillonite material has a great adsorption potential. Finally, it is proposed that the combination of advanced oxidation and composite montmorillonite material adsorption to remove heavy metal ions is an important direction of adsorption and removal of heavy metal ions in the water environment in the future.

“…This is due to high removal efficiency, ease of application and operation. Moreover, the adsorbents should be effectively low cost, environmentally friendly, practicable alternative properties and favorable for commercial purpose (Elsherbiny, El-Hefnawy et al 2017, Huang, Kankanamge et al 2018.…”

Cationic ligand exchange is one of the most predominant mechanisms for the removal of ammonia from wastewater through complex formation. The complexation technique occurs between the metal ions loaded on the surface of Amberlite IR-120 (R-H) and ammonia which is present in medium. Cu(II)-loaded Amberlite IR-120 (R-Cu2+) was prepared and described using FT-IR, TGA, XRD, SEM, EDX techniques. The prepared R-Cu2+ was applied for elimination of ammonia from aqueous solution. Different cations such as Co2+, Ni2+ were loaded onto Amberlite IR-120 to study the impact of counter cation on the removal efficiency of ammonia. The ammonia removal percentage followed the order; R-Cu2+ > R-Ni2+ > R-Co2+. The removal of ammonia using R-Cu2+ obeyed Freundlich isotherm model. Thermodynamic parameters characteristics of the adsorption of ammonia onto R-Cu2+ were determined. The time-adsorption data were followed the pseudo-second-order and intraparticle diffusion models. Moreover, the resulting product (R-Cu(II)-amine composite) from the adsorption process exhibited high catalytic activity and could be applicable as low cost catalyst for enhancement the elimination of dyes from wastewater.
