The adsorbent was prepared by coating a synthetic polymer on magnetite nanosphere surface as a magnetic carrier. The synthesized nano-adsorbent was fully characterized using Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometer, X-ray diffractometer, scanning electron microscope, and transmission electronic microscopy measurements. The synthesized nano-adsorbent showed high adsorption capacity towards removal of some anionic dyes (221.4, 201.6, and 135.3 mg g−1 for reactive red 195, reactive yellow 145, and reactive blue 19 dye, respectively) from aqueous samples. The dye adsorption was thoroughly studied from both kinetic and equilibrium points of view. It was found that the Langmuir isotherm showed a better correlation with the experimental data. The kinetic data showed that the process was very fast, and the adsorption process followed pseudo-second order kinetic models for the modified magnetic nano-adsorbent. Furthermore, the results showed that a stable and reusable (up to 20 cycles) nano-adsorbent for dye removal purposes was synthesized. adsorption, anionic dyes, dye removal, magnetite nanospheres, polymeric adsorbent © IWA Publishing 2017 You do not currently have access to this content.
