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

This work deals with the synthesis of ZnFe2O4 NPs and studies effect addition on physical properties PVDF/PVC blend. XRD affirmed formation HRTEM shows that size prepared ranged from 20 to 55 nm. The behavior was studied through XRD, ATR-FTIR, FESEM UV–Visible spectroscopy. revealed enhanced crystallinity blend system also confirmed incorporation by appearing a diffraction peak at 2θ equals 35°. ATR-FTIR interaction between sample new bands 554 cm−1 421 which are corresponded functional group band 603 cm−1. showed improved surface properties, for example, roughness average has been increased 319 414 nm while maximum height 260 473 PVDF/PVC/10% ZnFe2O4, respectively. Optical gap calculations changes structure polyblend samples results due localized states. removal efficiency Cd (II) using reached about 50% pH 6 after 60 min. absorption mechanism as well kinetics isotherm have studied. It is found adsorption occurred Langmuir fellow pseudo-second order isotherm.
