The adsorption of Congo red (CR) onto maghemite nanoparticles (J–Fe2O3), and itsdesorption was investigated. The adsorption capacity was evaluated using both the Langmuir and Freundlich adsorption isotherm models. Maghemite nanoparticles (J– Fe2O3) were prepared easily in a surfactant–less microemulsion, by co–precipitation method. The size of the produced maghemite nanoparticles was determined by X–ray diffraction (XRD) analysis and scanning electron microscopy (SEM). Synthesized maghemite nanoparticles showed the highest adsorption capacities of CR compared to many other adsorbents and would be a good method to increase adsorption efficiency for the removal of CR in a wastewater treatment process. The maximum adsorption occurred at pH 5.9. The Langmuir adsorption capacity (qmax) was found to be 208.33 mg\g of the adsorbent.<\div>
