Surface modified magnetite nanoparticles (Fe3O4 NPs) were synthesized by the one pot co-precipitation method using L-methionine (L-Met) as a capping agent. As synthesized Fe3O4 NPs have been characterized by using UV-Visible spectroscopy, FTIR spectroscopy, powder XRD, SEM-EDX and TEM. Magnetic property of L-Met capped Fe3O4 NPs was investigated by vibrating sample magnetometer (VSM). The XRD results indicated that formation of pure phase Fe3O4 NPs. The spectroscopic (FTIR and UV- Vis spectroscopy) results further confirm the effective capping of Fe3O4 NPs using L-Met. The VSM curve clearly depicts the superparamagnetic behavior of L-Met capped Fe3O4 NPs with saturation magnetization value of 65 emu/g. The kinetic studies for Rhodamine B (RhB) adsorption showed rapid adsorption within the first 40 min and sorption process best linear fitted to second-order kinetic model, suggesting chemisorption mechanism. Dye adsorption equilibrium data were fitted well to the Langmuir isotherm. (C) 2016 Published by Elsevier B.V.
