“…Since abundant active sites on the surface of FSMAA available for adsorption were gradually occupied by MB with the increase of time, the adsorption of MB was very fast in the initial stage, then increased slightly and finally reached a plateau, as illustrated in Figure 7a; this phenomenon was also observed in other adsorption experiments [28]. Pseudo-first-order and pseudo-second-order kinetic models were used to analyze the kinetic data, as shown in Figure 7b,c.…”

The removal of methylene blue (MB) from wastewater has attracted global concerns. In this study, polymer-functionalized magnetic nanoparticles for MB removal, Fe3O4@SiO2-MPS-g-AA-AMPS (FSMAA), were successfully synthesized by grafting acrylic acid (AA) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) on the surface of vinyl-modified Fe3O4@SiO2. With various characterization techniques, it was confirmed that the obtained FSMAA had a core–shell structure, a good magnetic property, and plenty of functional groups on its surface. MB adsorption experiments showed that the adsorption capacity of FSMAA was notably enhanced as the grafted monomer concentration and solution pH were increased. The adsorption kinetic data and isothermal data were well described by the pseudo-second-order kinetic model and the Langmuir model, respectively. The maximum adsorption capacity of FSMAA was 421.9 mg g−1 with grafted monomer concentration at 2.0 mol L−1 and solution pH at 9, much higher than those of other adsorbents stated in previous literatures. Based on XPS analysis, surface adsorption mechanism between FSMAA and MB was electrostatic interaction, hydrogen bonding, and hydrophobic interaction. Furthermore, FSMAA was effectively regenerated by acid pickling, and the remaining adsorption capacity was more than 60% after eight adsorption–regeneration cycles. All the results demonstrated the self-made FSMAA was a desirable adsorbent to remove MB from wastewater.

Yield cultivation of magnetotactic bacteria and magnetosomes: A review

Magnetotactic bacteria (MTB) have started to be employed for the biosynthesis of magnetic nanoparticles, due to the rapidly increasing demand for nanoparticles in biomedical, biotechnology and environmental protection. MBT are the group of prokaryotes that have the ability to produce bio-magnetic minerals or bio-magnetic crystals of either magnetite (Fe O ) or greigite (Fe S ) in numerous shapes and size ranges, known as magnetosomes (MS). MS compel MTB to respond to the applied external magnetic field. However, it is extremely difficult to grow MTB and produce high yield of MS under artificial environmental conditions, thus creating a major hurdle to relocate MTB technology from laboratory scale to industrial or commercial level. Therefore, to best of our knowledge this review is the first attempt to highlight existing research developments about the laboratory scale and mass production of MS by MTB. Moreover, the optimum culture media and environmental conditions used for the cultivation of MTB were also considered. Finally, future research is encouraged for the improvement of MS yield which will result in the development of advanced nanotechnology/magnetotechnology.

“…The results are similar to the formerly reported works. Lingamdinne et al reported almost similar XRD pattern of Fe‐NPs produced biologically by using Cnidium monnieri (L.) Cuss seed extract. Huang et al also represented nearly identical XRD trend in case of biologically produced Fe‐NPs using tea extract which proved to be very efficient for eliminating malachite green from the water.…”

Present work deals with the facile and ecologically viable production of iron nanoadsorbents by utilizing different waste plant biomass, orange peel, flower waste, and environmentally harmful Alligator weed. The as‐prepared nanoadsorbents were applied for the aqueous phase minimization of toxic dyes, alizarin red S and tartrazine. Different techniques, namely, X‐ray diffraction, Fourier transform infra‐red spectroscopy, scanning electron microscopy, dynamic light scattering and magnetic properties measurement system, were applied to characterize the synthesized material. Impact of various experimental conditions like pH, adsorbent dose, contact time, and temperature on removal trend was examined. The acidic medium positively favored the process of sorption. Kinetic analysis revealed that the adsorption of both the dyes followed pseudo‐second‐order kinetic model. Equilibrium sorption data were fitted better to Freundlich model as compared with Langmuir model. The maximum adsorption capacities at 50°C were 42.58 and 68.78 mg g–1 for alizarin red S and tartrazine at pH 4.0 and 2.0, respectively. Thermodynamic parameters exhibited that the sorption of both the dyes onto nanoadsorbent was spontaneous and endothermic with increased randomness at the solid–liquid interface. Desorption experiment demonstrated that the regenerated adsorbent can be recycled efficiently up to three times. Overall, the prepared nanomaterials exhibit remarkable removal competency for both dyes tested like alizarin red S and tartrazine.
