Ceramic membranes (Al2O3/TiO2) used for separation glycerol from biodiesel using response surface methodology

Green synthesis process has been developed to produce MgO nanoparticles using wet chemical method. In this process, Madhuca longifolia (M. longifolia) flower extracts has been used as a reducing and stabilizing agent and magnesium nitrate hexahydrate is used as a metal precursor. This study exhibits the effect of varied concentrations of metal precursors and flower extracts on the shape and size of the MgO nanoparticles. FTIR, UV vis spectroscopy, SEM, EDS and HRTEM analysis have been carried out to identify the functional groups involved in the reduction process, confirmation of MgO nanoparticles, morphological and elemental analysis of the MgO nanoparticles respectively. The results confirmed the presence of spherical MgO nanoparticles decorated over the surface of MgO microclusters. It is observed that the varying concentration of flower extracts and precursor have a profound effect on morphology of the nanoparticles resulting in the decrease in cluster size with the increase in extract concentration. The nanoparticles were also tested for the presence of antibacterial activity against the bacterial species of Escherichia coli and Staphylococcus aureus. © 2022 Taylor & Francis Group, LLC.

Development of MgO nanoparticles via green synthesis at varying concentrations of precursor and mahua flower extract

Thermoplastic PVC matrix was reinforced with waste fiber portion of Citrus Maxima (CM) fruit for making composites. The CM fibers were separated, dried at 50-60 °C for 24 h, coarse ground and sieved. PVC/CM fiber composite film with different fiber loading (10-70 wt%) were cast using solvent casting method. Sheets were cast in large petri dish using tetrahydrofuran (THF) as solvent and dried in an oven thoroughly at 50-60 °C. The evaluation of mechanical properties was done as per ASTM D882; stereo image of the fractured specimen and FTIR was used for the study of morphology and microstructure of the composite. Incorporation of fibers into PVC made the material stiff, leading to significant increase in Tensile Modulus, Breaking Strength and Yield Stress at higher filler loadings. Uniform distribution of the fibers in the microstructure of PVC matrix led to the formation of cross-ply structure and improved the mechanical properties. These results indicate that the fiber portion from CM can be effectively used as an eco-friendly reinforcing additive to form PVC composites.

The degradation of Rhodamine-B (RB) in aqueous solutions was investigated in this study under the influence of ultrasound irradiation (20 kHz) in the presence of titanium dioxide (TiO2) and niobium pentaoxide (Nb2O5) heterogeneous catalysts. The effects of different factors such as catalyst quantity (0.25, 0.5, 0.75, 1.0, 1.25 g/L), initial concentration of RB (10, 20, 30, 40, 50 ppm) and pH (3, 5, 7, 9, 11) were examined. The optimal catalyst dose was found to be 1.25 g/L of TiO2, Nb2O5and the maximum percentage of RB degradation was observed at pH 3 for the TiO2and Nb2O5catalysts. In the presence of TiO2and Nb2O5, the percentage degradation of RB under ultra-sonication in aqueous solutions is up to 85% and 81% respectively. © 2021 Elsevier Ltd. All rights reserved.

In this study, Polyethylene glycol is used as a water-soluble polymer to enhance separation efficiency of heavy metal nickel ion The complexion-Nanofiltration technique was used for separation of heavy metal ions. Polyethene glycol form complex with heavy metal ion and increases the separation efficiency. The effects various parameters like pH, Concentration and flow rate on the separation efficiency of heavy metal ion were evaluated. The optimum condition for separation of heavy metal ion was found at pH 10, Concentration (heavy metal ion) 200ppm, and flow rate 3(l/hm2). It was found that the addition of water-soluble polymer gives higher separation efficiency than without water-soluble polymer PEG. © IJSTR 2020.

Influence of water soluble polymer on nano-filtration membrane for separation of nickel ion.

In this study, an aqueous solution containing amixture of heavy metal ion Cr(III) were treated by polymerenhanced Nanofiltration using polyethylene glycol as a bindingagent polymer. The performance of PEG in removing heavymetal ion Cr (III) was compared with PEG and without PEGaddition using polyamide Nano filtrationmembrane. Thepercentage rejection of heavy metal ions was studied under thedifferent value of pH, metal ion concentration and flow rate.AtpH 10,percentage rejection of heavy metal ion was highest ataround 99.2%,whereas,at 200ppm concentration and at3(l/hm2)flow rate percentage rejection of heavy metal ion withPEG was highest 99.5%,it was found that PEG gave higherpercentage rejection of Cr(III) ion than without the addition ofPEG.
