“…In recent times, the development of adsorbents based on two or more metal oxides has attracted the attention of researchers worldwide, as binary oxide not only procures the characteristics of the parent compound but also displays synergistic effects [ 18 ]. This synergistic effect is evident from the enhanced adsorption capability in many recent studies [ 19 , 20 ]. For example, Fe–Mn binary oxides were found to be successful in removing arsenic ions from groundwater [ 21 ].…”

Nanotechnology has received much attention in treating contaminated waters. In the present study, a facile co-precipitation method was employed to synthesize a novel iron and magnesium based binary metal oxide using a stoichiometrically fixed amount of FeNO3.9H2O and MgNO3.6H2O in a proportion of molar concentration 1:1 and was later evaluated in removing As (III) from contaminated waters. Characterization of the prepared nanomaterial was done using X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy Dispersive X-Ray Analysis (EDAX) and ultraviolet–visible spectrophotometry (UV-VIS). Experimental studies on batch scale were carried out, examining the effect of varying initial concentrations of metal, adsorbent dosage, application time and initial pH on removal efficiency. Arsenic removal increased on increasing adsorbent dosage (0.1–1 g/L) but trend reversed on increasing initial arsenic concentration attaining qmax of 263.20 mg/g. Adsorption was quite efficient in pH range 4–8. Freundlich fitted better for adsorption isotherm along with following Pseudo-2nd order kinetics. The reusability and effect of co-existing ions on arsenic adsorption, namely SO42−, CO32− and PO43− were also explored with reusability in 1st and 2nd cycles attained adsorptive removal up to 77% and 64% respectively. The prepared nano-adsorbent showed promising results in terms of high arsenic uptake (qmax of 263.20 mg/g) along with facile and cost-effective synthesis. Thus, the co-precipitation technique used in this work is a simple one step procedure without any use of any precursor as compared to most of the other procedures used for synthesis.

“…Several researchers emphasized the use of manganese dioxide (MnO2) for the oxidation of As(III) as a result of its weak oxidation tendency, which is compatible with the specific oxidation of As(III) (Zhang et al, 2017). Moreover, co-occurring oxidation of As(III) to anionic As(V) and further adsorption of As(V) by iron binary oxides (Fe-Mn) leads to superior removal of arsenic with reduced contaminant mobility (Shan and Tong, 2013;Nikić et al, 2021).…”

“…Fe-based nanomaterials exhibit high surface area, chemical stability, adequate surface distribution of reactive sites, selectivity towards arsenic species, biocompatibility, and notable arsenic adsorption efficiency (Zhang et al, 2019;Nguyen et al, 2020;Nikić et al, 2021). Moreover, facile synthesis methods and efficient magnetic separation of Fe-based nanomaterials from treated water have increased the usability of this class of nanomaterials in arsenic removal processes (Chen et al, 2013a;Deng et al, 2019).…”

“…Thus, alkaline solutions are often used for the desorption of anionic pollutants, while acidic solutions remove cationic contaminants from adsorbent surfaces (Wang et al, 2020). Numerous studies (Figure 5) have reported using NaOH, HCl, NaCl, and NaOCl to regenerate iron nanomaterialbased adsorbents (Rajesh Kumar et al, 2016;Yu et al, 2018;Nikić et al, 2021). However, NaOH was commonly used for arsenic desorption from iron nanomaterial-based adsorbents.…”

Arsenic decontamination is a major worldwide concern as prolonged exposure to arsenic (>10 µg L-1) through drinking water causes serious health hazards in human beings. The selection of significant, cost-effective, and affordable processes for arsenic removal is the need of the hour. For the last decades, iron-oxide nanomaterials (either in the magnetite or bimetallic form) based adsorptive process gained attention owing to their high arsenic removal efficiency and high regenerative capacity as well as low yield of harmful by-products. In the current state-of-the-art, a comprehensive literature review was conducted focused on the applicability of iron-based nanomaterials for arsenic removal by considering three main factors: (a) compilation of arsenic removal efficiency, (b) identifying factors that are majorly affecting the process of arsenic adsorption and needs further investigation, and (c) regeneration capacity of adsorbents without affecting the removal process. The results revealed that magnetite and bimetallic nanomaterials are more effective for removing Arsenic (III) and Arsenic (V). Further, magnetite-based nanomaterials could be used up to five to six reuse cycles, whereas this value varied from three to six reuse cycles for bimetallic ones. However, most of the literature was based on laboratory findings using decided protocols and sophisticated instruments. It cannot be replicated under natural aquatic settings in the occurrence of organic contents, fluctuating pH and temperature, and interfering compounds. The primary rationale behind this study is to provide a comparative picture of arsenic removal through different iron-oxide nanomaterials (last twelve yearsof published literature) and insights into future research directions.

“…A manganese iron binary oxide was grafted onto the surface of iron oxide nanoparticles (average size, 21 nm) by Agbaba et al [133] who then tested this material for the removal of arsenic species from water. These composite materials were found to have maximum adsorbance capacities of 55.9 mg•g −1 for As(III) and 54.1 mg•g −1 for As(V) at pH 7.…”

Water resources are of extreme importance for both human society and the environment. However, human activity has increasingly resulted in the contamination of these resources with a wide range of materials that can prevent their use. Nanomaterials provide a possible means to reduce this contamination, but their removal from water after use may be difficult. The addition of a magnetic character to nanomaterials makes their retrieval after use much easier. The following review comprises a short survey of the most recent reports in this field. It comprises five sections, an introduction into the theme, reports on single magnetic nanoparticles, magnetic nanocomposites containing two of more nanomaterials, magnetic nanocomposites containing material of a biologic origin and finally, observations about the reported research with a view to future developments. This review should provide a snapshot of developments in what is a vibrant and fast-moving area of research.
