Tunning the Physical Properties of PVDF/PVC/Zinc Ferrite Nanocomposites Films for More Efficient Adsorption of Cd (II)

Abstract

This work studies the enhancement of the physical properties PVDF/PVC blend by adding ZnFe2O4 with different weight percent (from 0% up to 10%) as a nanofiller. The effect of ZnFe2O4 on behavior of PVDF/PVC was studied through XRD, FTIR, FESEM and UV-Visible spectroscopy. The PVDF/PVC/ 10% ZnFe2O4 nanocomposite film was represented the optimum sample. As it shows maximum crystallinity, roughness average (414 nm) and root mean square roughness (113nm) on another hand this sample has also the lowest value of energy band gap for direct and indirect transition. The removal efficiency of Cd(II) by using PVDF/PVC/ 10% ZnFe2O4 reached to about 50 % at pH 6 after 60min. the absorption mechanism as well as kinetics isotherm have been studied.

High‐Performance of Self‐Powered UV–Visible CdS (PVP)/PbI2 Heterojunction Photodetector

“…Due to the high-temperature annealing causing polymer volatilization and low PVP content, XRD analysis was performed separately on single-layer PVP and single-layer CdS (PVP), as shown in Figure S1, Supporting Information. The two patterns have the same wave packet and the position at 15°< 2θ < 35°is consistent with the previous PVP patterns, [31,32] which indicates the existence of PVP. In Figure 2a, the diffraction peaks at 24.83°, 26.53°, and 28.21°a re correspond to (100), (002), and (101) crystal planes of CdS (PDF#75-1545), respectively.…”

Study the multiferroic properties of BiFeO3/Ni0.1Fe2.9O4 for heavy metal removal

“…It is clear that χ M decreases as temperature as well as field intensity increases. By increasing magnetic field intensity, the alignment of dipoles along field direction is increasing in other hand, because of rising temperature, thermal energy increases dipoles disorder, and as a result, magnetic susceptibility decreases gradually until reaching zero (Curie temperature) [24][25][26].…”

“…The Langmuir isotherm is related to monolayer adsorption at comparable sites and similar adsorption energies [25]. Although, Freundlich isotherm is attributed to dissimilar surfaces [32].…”

Synthesis, characterization and application of chitosan/graphene oxide/copper ferrite nanocomposite for the adsorptive removal of anionic and cationic dyes from wastewater

“…By anchoring magnetic NPs into solid sorbents, the separation and selective pollutant's removal can be achieved even in the presence of other solids. 21 Due to their chemical, magnetic, and thermal features, spinel ferrites NPs are often utilized as magnetic supports for adsorbents. 22 Among these spinal ferrites, CuFe 2 O 4 has attracted substantial applied and fundamental research attention due to its numerous uses in electronics, sensors, and catalysts.…”
