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 including
X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared
spectroscopy (FT-IR). Then, the potential of malicorium supported Ni0.5Zn0.5Fe2O4 magnetic
nanoparticles was investigated for adsorption of Manganes (II). The effect of different parameters
including contact time, pH, adsorbent dosage and initial Mn (II) concentration on the Mn (II) removal
yield was studied. The experimental data were fitted well with the Langmuir isotherm model. The
maximum monolayer adsorption capacity based on Langmuir isotherm is90.91 mg g-1. The prepared
magnetic adsorbent can be well dispersed in the aqueous solution and easily separated from the
solution with the aid of an external magnet after adsorption. The process for purifying water treatment
presented here is clean and safe using the magnetic nanoparticles. Therefore, this adsorbent was
considered to be applicable for managing water pollution caused by Mn (II) ions.
