Abstract :

Malicorium supported Ni0.5Zn0.5Fe2O4 magnetic nanoparticles were synthesized by a low-cost, simple,and environmentally benign procedure. The adsorbent was characterized by several methods includingX-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infraredspectroscopy (FT-IR). Then, the potential of malicorium supported Ni0.5Zn0.5Fe2O4 magneticnanoparticles was investigated for adsorption of Manganes (II). The effect of different parametersincluding contact time, pH, adsorbent dosage and initial Mn (II) concentration on the Mn (II) removalyield was studied. The experimental data were fitted well with the Langmuir isotherm model. Themaximum monolayer adsorption capacity based on Langmuir isotherm is90.91 mg g-1. The preparedmagnetic adsorbent can be well dispersed in the aqueous solution and easily separated from thesolution with the aid of an external magnet after adsorption. The process for purifying water treatmentpresented here is clean and safe using the magnetic nanoparticles. Therefore, this adsorbent wasconsidered to be applicable for managing water pollution caused by Mn (II) ions.
