Use of Nano-Magnetic Material for Removal of Heavy Metals from Wastewater


The reason of this study is to consider the removal of heavy metal lead (Pb) and cadmium (Cd) in wastewater by magnetic material using ferrite. It has been use batch experiments and operating condition are, ph(10,7and5) and time (20, 40, 60.80.100, 120) min and temperature (30) 0C after that we find the optimum condition to remove heavy metal. heavy metal in water detected by using Atomic Absorption (AA) before and after adding Cu-ferrites powder while the Cu-ferrites was characteristic by XRD and SEM ,result indicate that Cu-ferrites powder spinel structure and the particle size in range (30-40)nm ,and explain antimicrobial effectiveness of ferrites material from effect on gram positive and negative bacteria and the results appeared ability of copper ferrites to inhibition growth of both E. coli as example of gram negative bacteria and S. aureus as example of gram positive bacteria while was the E. coli survival rate of all ferrite nanoparticles concentration is more than the S. aureus survival rate , the percentage survival of bacteria was ( 35 , 20 , 12 , 5 %) in (0.625 , 1.25 , 2.5 , 5 mg/ml) concentration of microorganisms E.coli and ( 28 , 15 , 8 , 3 %) in (0.625 , 1.25 , 2.5 , 5 mg/ml) concentration for bacteria Staph.
