The characterization of the modified resin was performed using Field Emission Scanning Electron Microscopy (FESEM), Fourier-transform infrared spectroscopy (FTIR), and Energy-dispersive X-ray (EDX) spectroscopy. Batch adsorption experiments under various conditions, such as time, temperature, pH and amount of adsorbent were carried out to evaluate the adsorption characteristics of magnetite-loaded resin in the removal of Cr(III) from aqueous solutions. The adsorption of Cr(III) on modified resin was found to obey the Langmuir adsorption isotherm with maximum adsorption capacity of 32.72 mg/g, which much higher than unmodified resin (23.87 mg/g) under the same optimum conditions. Therefore, it was proven that modification of ion exchange resin with magnetite nanoparticles significantly improves the adsorption performance for Cr(III) removal.</p>}, number={2}, journal={Journal of Applied Membrane Science & Technology}, author={Jaffar, F.
