Adsorption of methylene blue and rhodamine B on graphene oxide-Fe<sub>3</sub>O<sub>4</sub> nanocomposite: Molecular dynamics and Monte Carlo simulations
Abstract
<jats:p>Graphene oxide based magnetic nanocomposite (GO-Fe<jats:sub>3</jats:sub>O<jats:sub>4</jats:sub>) was synthesized using the coprecipitation method. Intercalation of nanoparticles has resulted in the modified interlayer spacing of GO sheets, it is increased from 0.82 to 1.11 nm. Nanocomposite was characterizedusing TEM, AFM, XRD, UV-Visible and Raman spectroscopy. Magnetic nanocomposite is tested for removal of industrial dyes MB and RB through the adsorption process. The adsorbent dosage, dye concentration, and adsorption time are optimized in an optimal condition in the dye removal experiments(0.1 g/L adsorbent (GO), 10 mg/L of MB and RB with 25 minutes adsorption time). Adsorption capacity of 100 and 80 mg/g was achieved for MB and RB respectively. Preferential behavior of nanocomposite towards MB over RB can be attributed to the differential electrostatic and geometrical interactions.Differential behavior towards adsorption of dyes is further studied by Monte Carlo adsorption locator and molecular dynamics simulations. Adsorption energies corresponding to MB/GO, RB/GO, MB/Fe<jats:sub>3</jats:sub>O<jats:sub>4</jats:sub>, and RB/Fe<jats:sub>3</jats:sub>O<jats:sub>4</jats:sub> systems show that certain configurationsfavor adsorption on GO and Fe<jats:sub>3</jats:sub>O<jats:sub>4</jats:sub> surfaces. Radial distribution function calculation shows the geometric separation of 2.23 and 5.13 Å for MB and RB respectively, which has profound effect on electrostatic and <jats:italic>π-π</jats:italic> interaction.</jats:p>
