Abstract

The present study is focused on the preparation and characterization of magnetized polymer clay nanocomposites and its application in the removal of Cr(VI) from aqueous solution. Polymer clay composites were prepared from bentonite clay via in situ emulsion polymerization using methyl methaacrylate as monomer. The prepared polymer clay composites were magnetized by the incorporation of iron oxide nanoparticles. The magnetized polymer clay (MPC) nanocomposite was characterized by FT-IR, FE-SEM, VSM and TGA. Magnetized polymer clay nanocomposites had uniform distribution of iron oxide nanoparticles of size around 80 nm and had good thermal stability. Batch equilibrium studies were carried out and the experimental results were modelled using Langmuir, Freundlich and Temkin isotherm models. The maximum monolayer adsorption capacity was found to be 113 mg/g for the adsorption of Cr(VI) onto MPC nanocomposites. Kinetic studies were carried out and the data were tested with pseudo first-order and pseudo second-order equations. Adsorption of Cr(VI) onto the prepared nanocomposites was initially by film diffusion followed by intraparticle diffusion.
