Journal Article 2021 12 21 [(Cured epoxy resin- lignin) nanomagnetic interpenetrating polymer network (IPN)] (NM - IPN’s) derived from cured epoxy with amine hardener and Lignin was synthesized by sequential polymerization in the presence of Fe3O4 nanomagnetic particles. The chemical structure and surface morphology of NM semi 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 semi IPNS) have been evaluated by Thermogravimetric analysis (TGA) and Differential Scanning Calorimetric (DSC). Adsorption of Cu+2, Pb+2, Co+2 and Cd+2 was investigated under different conditions such as pH and time using flameless atomic absorption spectroscopy. The adsorption studies were evaluated by using Langmuir and Freundlich isotherms. https://jns.kashanu.ac.ir/article_111885_8fae9548db12085862e80abc0f9ead97.pdf
