“…It also signifies that the leaf extract acts as a reducing agent and may cause the reduction of the iron. The results are in agreement with studies carried out by other researchers reported in literature [51,52] and the little variation of peaks might be due to the presence of different phytochemicals in the plant material. Scanning electron microscope images showed that IONPs formed are round in shape with less discrete particles, and the size is less than 100 nm (Figure 2a).…”

This study demonstrates the ecofriendly synthesis of iron-oxide nanoparticles (IONPs) and their stabilization with polymers, i.e., chitosan (C) and polyvinyl alcohol (PVA)-alginate (PA), along with a further investigation for the removal of arsenic(As(V)) from water. IONPs with an average diameter of less than 100 nm were prepared via a green synthesis process using an aqueous leaf extract of Terminalia chebula. Batch experiments were conducted to compare the removal efficiency of As(V) by these adsorbents. Factors such as pH and adsorbent dosages significantly affected the removal of arsenate As(V) by IONPs and polymer-supported reactive IONPs. Several adsorption kinetic models, such as pseudo first-order, and pseudo second-order Langmuir and Freundlich isotherms, were used to describe the adsorption of As(V). The removal of As(V) by IONPs follows the Langmuir adsorption isotherm. The highest monolayer saturation adsorption capacity as obtained from the Langmuir adsorption isotherm for IONPs was 28.57 mg/g. As(V) adsorption by polymer-supported IONPs best fit the Freundlich model, and maximum adsorption capacities of 34.4 mg/g and 40.3 mg/g were achieved for chitosan-and PVA-alginate-supported IONPs, respectively. However, among these absorbents, PVA-alginate-supported IONPs were found to be more effective than the other adsorbents in terms of adsorption, stability, and reusability.Among the various water treatment technologies, adsorption seems to be a more convenient and effective method for the removal of heavy metals in terms of cost and simplicity of process [10]. Iron and related adsorbents are popular for the remediation of water pollutants [11]. The intervention of nanotechnology opened a new horizon in the field of water purification [12]. Iron nanoparticles (NPs), which possess a high surface area and surface reactivity, are effectively used for water treatment [13,14]. Zero-valent iron nanoparticles (nZVIs) and iron oxide nanoparticles, such as Fe 2 O 3 and Fe 3 O 4 NPs, are among those commonly employed for the remediation of environmental pollution, particularly for the decontamination of water [15][16][17][18]. Magnetic nanoparticles and modified magnetic nanoparticles were found to be very effective for the removal of arsenic because of their strong adsorption activities, and they can be easily separated by employing an external magnetic field [19][20][21]. Evidence of the particle size influence on the ability to remove (adsorb) arsenic from water was observed, as smaller nanoparticles were found to exhibit more adsorption capacity and faster kinetics due to their higher specific surface area, shorter intraparticle diffusion distance, and larger number of surface reaction sites of nanoparticles [22,23]. The nanopowder form of metal oxides/hydroxides provides a high surface area for increased adsorption capacity; however, this small particle size also drives the need for energy-intensive post-treatment filtration to recover the nanoparticles for regeneration and reuse [24]. To overcome this issue,...

“…Biosynthesis can be carried out either by using different microrganisms or by using extract of different plants parts such as extract of root, stem, leaves, bark, flower and seeds etc. [16] [19] [20]. Moreover, plant based synthesis are more popular as they are natural, renewable, safe to handle and easily accessible [21].…”

Because of various disadvantages of chemical synthesis processes, these days people are attracting towards green synthesis processes as it is devoid of toxic by-products, cost-effective and eco-friendly. In this study, a simple green synthesis method is applied for the synthesis of magnetite (Fe 3 O 4) nanoparticles (MNPs) by co-precipitation of FeCl 3 •6H 2 O and FeSO 4 •7H 2 O in the molar ratio of 2:1 using Azadirachta indica leaves extract under nitrogen environment. FTIR, XRD, SEM etc. were used to characterize the synthesized MNPs. Batch adsorption experiments were carried out to determine adsorption equilibrium of As(V) as a function of pH, adsorbent dose, contact time and different initial concentrations. Kinetics results were best described by pseudo-second order model with rate constant value 0.0052 g/(mg•min). The equilibrium adsorption isotherm was best fitted with Langmuir adsorption isotherm model. The maximum adsorption capacity was found to be 62.89 mg/g at pH 2. MNPs showed a high affinity for As(V) and avoids filtration for solid-liquid separation, thus it would be employed as a promising material for the removal of As(V) from water.

Magnetic nanoparticles are promising approaches for cancer treatment. Iron oxide nanoparticles have been pre-formed by the co-precipitation method to investigate their antitumor activity on Ehrlich carcinoma in mice. The nanoparticles have been studied by UV spectrophotometer, transmission electron microscopy, dynamic light scattering, and zeta potential measurement. To determine the therapeutic impact of Iron oxide nanoparticles in tumorbearing mice, in vivo experiments were carried out. Fourier Transform Infra-red (FTIR) spectroscopy and DNA comet assay were used to estimate the toxicity of nanoparticles of iron oxide. The tissue was analyzed using FTIR spectral parameters such as the area beneath the peak, peak position, and peak intensity. The results showed that iron oxide nanoparticles significantly led to antitumor activity against Ehrlich carcinoma. There was a low shift in position and intensity at the amide I band (1650 cm −1 ) in tissues of mice treated with iron oxide nanoparticles compared to the control group. Comet examination showed a decrease across all the parameters of the assay (tail moment, tail DNA percentage, and tail length) in the tumor + iron nanoparticles group, having values lower than the tumor group. According to the presented results, Iron oxide nanoparticles have exhibited therapeutic efficacy against cancer.
