Abstract

The manganese cobalt ferrite (Mn1-xCoxFe2O4) of x = 0.25, 0.50, and 0.75 have been synthesized to determine the structure and magnetic properties to be used as an adsorbent to remove Pb ions from aqueous solution. The material was prepared using the co-precipitation method and the removal process was performed by the adsorption method. The crystal structure, morphology and the magnetic properties were characterized using x-ray diffraction (XRD), surface electron microscopy (SEM), and vibrating sample magnetometer (VSM), respectively. The crystallite size of the material (by increasing the amount of Co content) was about 28.06, 27.97, and 26.61 nm, respectively. The morphology of the sample tends to agglomerate, with the grain protruding on its surface. Moreover, the VSM analysis shows that the saturation magnetizations improve as the x value increased, while its coercivity was decreased which showed a superparamagnetic behavior. Further, the adsorption of Pb ions was analyzed using an atomic absorption spectroscopy (AAS). The result showed that the maximum adsorption capacity was obtained around 290.5 mg/g with an efficiency of 82.30 %. Therefore, this material has the potential application to be used as an adsorbent to remove the metal ions from wastewater.
