A study on the Removal of Heavy Metal ions from the Groundwater using some Magnetic Nanocomposite Materials

Abstract

Groundwater treatment is a real challenge in the past few decades, in Egypt groundwater is the second water resource that comprises about 20.65 billion m3/year, it is the major source of domestic water for people living in some rural and semi-urban areas in Egypt. Groundwater pollution produced by human activities lead to the presence of high levels of heavy metal ions, which is a cause of concern due to their acute and long term toxicity. Various efficient technologies have been developed for the treatment of the groundwater, while adsorption technology has been considered as an economical and efficient in water treatment for removal of metal ions. Nanotechnology has a wide application in water treatment field, where nanoscale materials have extremely small size and high surface area to volume ratio that provide better kinetics for the adsorption of target contaminants from aqueous solutions. Also magnetic nanomaterials as Fe304, NiFe204 and their composites with natural polymers are

promising in water treatment field, as a result of their superparamagnetism they exhibited unique electric and magnetic properties.
