Abstract
The increasing level of heavy metal ions in wastewater present a serious risk
for human health and ecological system because they are non-biodegradable. Magnetically assisted
chemical separation method using magnetic nanoparticles with a large active surface opens the
door to a new generation of waste water treatment technology. In the present work, magnetic
ZnO/ferrites nanoparticles were prepared to improve the efficiency of copper removal from
artificial water. The ZnO/ferrites nanoparticles were synthetized by hydrothermal method and
were characterized by several techniques. The adsorption properties as function of different
parameters were carried out in order to understand the mechanism of adsorption.
