Applicability of Ferromagnetic Nanoparticles in the Retention of Heavy Metals from Aqueous Solutions

In this paper are presented the experimental results obtained in the study of applicability of ferromagnetic nanoparticles in the retention of heavy metals from aqueous solutions. The influence of magnetic nanopartides based on iron, cobalt and nickel on turbidity, pH, permanganate index, aluminum, copper, cadmium and lead was studied. The study shows that conventional water treatment systems combined with acrylic polymer can be improved by adding magnetic nano articles. Experimental data has shown that the presence of magnetic nanoparticles based on iron, cobalt and/or nickel increases the efficiency of the treatment system and is reflected by all analyzed parameters.
