“…The IR spectrum from Figure 2 demonstrates the successful conjugation of EG molecules onto Fe 3 O 4 particles. The vibrational bands identified at~2928 cm −1 and~2848 cm −1 correspond to the asymmetric and symmetric stretching of -CH 3 originating from Eucalyptus essential oil [85], while the~558 cm −1 band is assigned to Fe-O stretching vibrations from magnetite [86,87].…”

The present study reports on the development and evaluation of nanostructured composite coatings of polylactic acid (PLA) embedded with iron oxide nanoparticles (Fe3O4) modified with Eucalyptus (Eucalyptus globulus) essential oil. The co-precipitation method was employed to synthesize the magnetite particles conjugated with Eucalyptus natural antibiotic (Fe3O4@EG), while their composition and microstructure were investigated using grazing incidence X-ray diffraction (GIXRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM) and dynamic light scattering (DLS). The matrix-assisted pulsed laser evaporation (MAPLE) technique was further employed to obtain PLA/Fe3O4@EG thin films. Optimal experimental conditions for laser processing were established by complementary infrared microscopy (IRM) and scanning electron microscopy (SEM) investigations. The in vitro biocompatibility with eukaryote cells was proven using mesenchymal stem cells, while the anti-biofilm efficiency of composite PLA/Fe3O4@EG coatings was assessed against Gram-negative and Gram-positive pathogens.

Sodium alginate (SAG) crosslinked poly (N,N-dimethyl Acrylamide-co-2 acrylamino-2-methyl-1-propane sulfonic acid)/Titanium dioxide [SAG-cl-poly (N,N-DMA-co-AMPS)/TiO 2 ] nanocomposite hydrogel (NCHG) was prepared by in situ crosslinked free radical polymerization technique using SAG, a mixture of DMA and AMPS and titanium isopropoxide in presence of methylenebis-acrylamide as a cross linking agent. Different characterization techniques are used to characterize NCHG. Water swelling behavior of NCHG together with swelling kinetics is evaluated. Maximum swelling (35% at 30 min) is observed at pH 8. NCHG is used for the removal of one cationic dye methylene blue (MB) and one anionic dye carmosine-A (CR-A) from their aqueous solution. Adsorption dynamics, kinetics and isotherms are evaluated. Maximum dye adsorption occurs at pH 8 and 2, at time 50 min for both the cases, at temperature 60 C, 40 C for MB and CR-A respectively. Pseudo-second order kinetics and Langmuir isotherm model are followed for all the two cases with Q max 403.22 mg.g À1 , 106.26 mg.g À1 and the R 2 value 0.9987 and 0.9950 for MB and CR-A respectively. Evaluation of thermodynamic parameters of the adsorption indicates that the adsorption is spontaneous in nature for the two dyes.

“…Membrane separation, flocculation, advanced oxidation and adsorption seem available techniques frequently used in general (Kamel et al 2020;). If adsorption techniques did indeed apply to adsorb pollutants simply and effectively, we would certainly lean to use this easy-designed and low-consumption process (Anjum et al 2019;Moharrami et al 2020;Zhang et al 2020).…”

“…A great deal of hydrophilic, as well as highly reactive hydroxyl and carboxyl groups existed in their polymeric scaffold, which played an active part in surface modifications, other substance could fairly easy grafting on the second, third and sixth carbon atoms (Arabkhani et al 2020;Li et al 2020). Cellulosic materials provided a great deal of attachment plaques and adsorption sites for organic contaminants as a result of their high specific surface area and porous structure (Kamel et al 2020;Chen et al 2020). In the meantime, the surface modification of cellulose was beneficial to improve its application fields (Alekseeva et al 2017) According to the literature, grafting hydrophilic monomers in the presence of cross linker could improve the utilization efficiency of wastewater with organic dyes.…”

A brand-new environmental-friendly magnetic cellulosic adsorbent MnFe2O4@Cel-g-p(AA-DMC) was synthesized by natural cellulose and easy-recovered magnetic particles MnFe2O4. Magnetic cellulose composites were characterized by SEM, TEM, XPS, XRD, BET, VSM, TGA and FTIR. The MnFe2O4NPs could activate the peroxymonosulfate (PMS) to produce various reactive oxygen species (ROS). Accordingly, magnetic cellulose composites can synergistic adsorption degradation of dyes from organic wastewater. The Congo red (CR) removal efficiency by MnFe2O4@Cel-g-p(AA-DMC) via PMS activated by MnFe2O4 reached a maximum of 96.9% and only 9% reduction after four adsorption-desorption cycles, indicating the stability and recoverability of adsorbent. It is worth noting that adsorbents can be quickly recovered from aqueous solution by external magnet owing to superior saturation magnetization (35.44 emu·g-1). A possible degradation mechanism of CR on the MnFe2O4@Cel-g-p(AA-DMC) composite was proposed. The results suggest that adsorbent display strong potential for the removal of CR dyes from organic wastewater.
