[Poly(Thiourea-Formaldehyde) - Epoxy resin)] Nanomagnetic Full -IPN's for Removal of Heavy Metals from Aqueous Solution : Synthesis and Characterization

Abstract

In this work, a batch adsorption study was conducted to investigate the removal efficiency of lead (II), Copper (II) and Cadmium (II) from aqueous solutions by (poly (thiourea-Formaldehyde-Epoxy resin) nanomagnetic Full-IPN's (NM Full-IPN's). The NM Full-IPN's was synthesized by sequential polymerization with presence Fe3O4 nanoparticles. The chemical structure and surface morphology of NM Full-IPNS resin nanoparticles were characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM). The chemical structure and surface morphology of NM Full-IPNS resin nanoparticles were characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM). The thermal properties of (NM Full- IPN's) has been evaluated by Thermogravimetric analysis (TGA) and Differential Scanning Calorimetric (DSC). Adsorption of Pb (II), Cu(lI) and Cd(II) onto NM Full- IPN's agreed well with the Langmuir model, as revealed by the higher values of correlation coefficients. The results indicate that NM Full- IPN's could be used as efficient adsorbent for the removal of Pb (II), Cu(lI) and Cd(II) from aqueous solution
