Water contaminated with highly hazardous metals including arsenic (As) is one of the major challenges faced by mankind in the present day. To address this pressing issue, hybrid beads were synthesized with various concentrations of zero valent iron oxide nanoparticles, i.e., 20% (FeCh-20), 40% (FeCh-40) and 60% (FeCh-60) impregnated into a polymer of chitosan. These hybrid beads were employed as an adsorbent under the optimized conditions of pH and time to facilitate the efficient removal of hazardous arsenic by adsorption cum reduction processes. X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Brunauer- Emmett-Teller BET, a porosity test and wettability analysis were performed to characterize these hybrid beads. The porosity and contact angle of the prepared hybrid beads decreased with an increase in nanoparticle concentration. The effects of various adsorption factors such as adsorbent composition, contact period, pH value and the initial adsorbate concentration were also evaluated to study the performance of these beads for arsenic treatment in contaminated water. FeCh-20, FeCh-40 and FeCh-60 have demonstrated 63%, 81% and 70% removal of arsenic at optimized conditions of pH 7.4 in 10 h, respectively. Higher adsorption of arsenic by FeCh-40 is attributed to its optimal porosity, hydrophilicity and the presence of appropriate nanoparticle contents. The Langmuir adsorption kinetics described the pseudo second order. Thus, the novel beads of FeCh-40 developed in this work are a potent candidate for the treatment of polluted water contaminated with highly toxic arsenic metals.

AbstractIn this study, a new one step paired electrochemical method is developed for simultaneous synthesis of iron and iron oxide nanoparticles. iron and iron oxide are prepared as cathodic and anodic products from iron (ii) sulfate aqueous solution in a membrane divided electrolytic cell by the pulsed current electrosynthesis. Because of organic solvent-free and electrochemical nature of the synthesis, the process could be considered as green and environmentally friendly. The reduction of energy consumption and low cost are the other significant advantages of this new method that would have a great application potential in the chemical industry. The nanostructure of prepared samples was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The magnetic properties were studied by vibrating sample magnetometer (VsM).

To elude the toxic effects of chemically synthesized nanoparticles, the phytochemically synthesized nanoparticles may provide a better alternative. For the first time, an aqueous extract of Juncus inflexus shoot with FeCl3.6H2O was used for the phytosynthesis of iron oxide nanoparticles (FeONPs). As-synthesized FeONPs were characterized by UV-Vis spectroscopy, Transmission electron microscopy (TEM), Dynamic light scattering (DLS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). FeONPs showed UV-vis absorption spectra between 300-400 nm, whereas TEM analysis confirmed the particle sizes of 40-60 nm with aggregation. XRD is confirming the polymorphic composition of Fe3O4, α-Fe2O3, and Fe0 nanoparticles. Furthermore, FTIR analysis presenting the most probable mechanism for the synthesis of FeONPs. This multiphase FeONPs was applied for the decolorization of methylene blue dye (>83%). Phytosynthesized FeONPs have the benefits of low cost, no toxicity, sustainable, and eco-friendly technology so that they may be used as adsorbent/catalyst for remediation of toxic dyes in an aqueous medium.

Aim: The primary goal of this work was to synthesize low-cost superparamagnetic iron oxide nanoparticles (SPIONs) with the aid of coconut water and evaluate the ability of macrophages to internalize them. Our motivation was to determine potential therapeutic applications in drug-delivery systems associated with magnetic hyperthermia. Materials & methods: We used the following characterization techniques: x-ray and electron diffractions, electron microscopy, spectrometry and magnetometry. Results: The synthesized SPIONs, roughly 4 nm in diameter, were internalized by macrophages, likely via endocytic/phagocytic pathways. They were randomly distributed throughout the cytoplasm and mainly located in membrane-bound compartments. Conclusion: Nanoparticles presented an elevated intrinsic loss power value and were not cytotoxic to mammalian cells. Thus, we suggest that low-cost SPIONs have great therapeutic potential.

Synthesis Of Nanoparticles

Studies on green synthesis of nanoparticles moves forward a lot on these days. The present work involves the green method of synthesizing iron oxide nanoparticle from Phyllanthus niruri leaf extract. Furthermore, the green synthesized iron oxide nanoparticles were characterized and its antimicrobial activity was investigated. A characteristic comparison with chemical method of synthesis is also done, for iron nanoparticles. The characterization of nanoparticle includes the IR, UV-Vis, surface morphology and size determination using TEM, SEM, and XRD. The analytical studies revealed that the synthesized iron oxide nanoparticles from these two different methods have almost identical size and morphology. The synthesized iron oxide nanoparticles showed significant antimicrobial activity against the microbes, E. coli and P. aeroginosa. The studies concluded that the synthesis of iron oxide nanoparticles using plant extracts is more beneficial as it is an economical, energy efficient, low cost and environment-friendly process than the bio hazardous chemical synthesis. The present investigation may be a definite contribution to green chemistry in general and nano synthesis in particular.

Abstract This study investigates the potential of iron oxide nanoparticles (Fe3O4) and quince seed mucilage (QSM) as combined genetic carriers to deliver plasmid DNA (pDNA) through the gastrointestinal system. The samples are characterized by XRD, zeta potential, DLS, FT-IR spectroscopy, FE-SEM and VSM. The stability of pDNA loading on the nanocarriers and their release pattern are evaluated in simulated gastrointestinal environments by electrophoresis. The XRD patterns reveal that the nanocarriers could preserve their structure during various synthesis levels. The saturation magnetization (Ms) of the Fe3O4 cores are 56.48 emu/g without any magnetic hysteresis. Not only does the loaded pDNA contents experience a remarkable stability in the simulated gastric environment, but also, they could be released up to 99% when exposed to an alkaline environment similar to the intestinal fluid of fish. The results indicate that the synthesized nanoparticles could be employed as efficient low-cost pDNA carriers.
