Elastomeric polyurethane (PU) and its composites (PUN and PUC) with different types of filler were prepared and investigated by differential analysis. Their ability to remove Pb 2+ ions from aqueous solutions was studied. The results indicated that, at high concentration of Pb 2+ ions (500 mg/L), the removal efficiency of Pb 2+ ions by PUC is better than PUN; at low concentration of Pb 2+ ions (125 mg/L), the difference in removals between the two is only slight, i.e., 58.36 % by PUC (0.5 g/L) and 55.11 % by PUN (0.5 g/L). Moreover, PUN exhibited a well-developed site structure, providing adsorption sites for Pb 2+ ions; for this and for cost reasons, we decided to study Pb 2+ ions removal ability of PUN. The results showed that the maximum adsorption capacity of Pb 2+ ions at 125 mg/L concentration at pH 5.0, when using 0.5 g/L of PUN as adsorbent, was 142.85 mg/g. Furthermore, the equilibrium data showed that the adsorption of Pb 2+ ions on PUN obeys a pseudo-second order kinetic model, depending on adsorbent dosage, pH, initial concentration of metal ions and contact time. From these results, it is suggested that PUN adsorbent may be appropriate for the removal of Pb 2+ ions from wastewater.

“…Therefore, in recent years, new interest has been arised in developing new applications for electrospun composite NFs. Considering the most attractive features of electrospun composite NFs, including high porosity, large surface area, easy separation, reusability, nonleaching nanostructured materials, and photocorrosion resistance of encapsulated nanostructure materials, a variety of applications related to water treatment [118,121,123,124,126,127,129], antibactericidal [119,122], hydrogen production [121,127], magnetic nanocomposite [125,128,130], and microwave absorption [131] have been highlighted in this communication.…”

“…Electrospun composite NFs consisting of magnetic nanostructures embedded within polymeric NFs have been under intensive investigation in the last years because such nanocomposite materials can also be used as protection materials of electromagnetic radiation as magnetic nanostructures show high frequency electromagnetic field absorption properties [131]. Chiscan O 4 NPs were encapsulated in PVC NFs with diameter range 100 nm and 600 nm.…”

ABSTRACT:The thermoresponsive magnetic polymer composites and nanofibers were fabricated. Their thermal and magnetic properties were also investigated. Fe 3 O 4 nanoparticles were prepared by coprecipitation method. Further condensation reaction was used to fabricate the double-layer lauric acid modified Fe 3 O 4 (DLF) nanoparticles dispersed well in water. Thermal properties of poly(N-isopropylacrylamide) (PNIPAAm) and DLF/PNIPAAm composites and their aqueous solutions were measured by TGA and DSC. With the increasing of DLF content, the interaction between DLF and PNIPAAm caused the lower critical solution temperature (LCST) of polymer solution to shift from 33 to 31.25 C. The effects of concentration and pH on LCST were also studied. The DLF/PNIPAAm nanofibers were fabricated by electrospinning. Their diameters were around 100-250 nm. Magnetization curves of DLF/PNIPAAm composite and nanofibers were overlapped and the saturated magnetizations were the same. Magnetic attraction behaviors of DLF/PNIPAAm polymer solution at temperatures below and above LCST were different. Aggregation of DLF/PNIPAAm above LCST enhanced magnetic moment density as well as magnetic attraction ability.
