Synthesis of poly(amidoamine)-graft-poly(methyl acrylate) magnetic nanocomposite for removal of lead contaminant from aqueous media

Abstract: Poly(amidoamine)-graft-poly(methyl acrylate) magnetic nanocomposite was synthesized via radical polymerization of methyl acrylate onto modified magnetic nanoparticles followed by the functionalization of the methyl ester groups with poly(amidoamine) dendrimer. The resulting poly(amidoamine)-graft-poly(methyl acrylate) magnetic nanocomposite was then characterized by infrared spectroscopy, transmission electron microscopy, thermogravimetric analysis, scanning electron microscope and X-ray diffraction analysis. … Show more

“…They found that the process of adsorption was pH dependent, and the adsorption capacity order was Pb 2+ > Cu 2+ > Cd 2+ > Ni 2+ , as illustrated in Figure 4 [186]. In another study, magnetic nanocomposites composed of G3-PAMAMgraft-poly (methyl acrylate) were created for the magnetic removal of Pb 2+ ions [187]. At pH 5-6, the maximum adsorption capacity (310 mg/g) was found.…”

“…In addition, iron oxide had poor solubility and tended to form iron hydroxide precipitation at low pH value, and it was not easy to form iron oxide gel. Pourjavadi et al (2016) polymerized methyl acrylate on the surface of activated magnetic particles and then grafted PAMAMs with methyl acrylate group to prepare magnetic nanocomposites (PAMAM-MNC). In general, the composite adsorbent obtained by modifying magnetic nano-material with PAMAMs has a certain potential application value for the development of heavy metal adsorption research.…”
