Abstract

Aluminum is the most widely used non ferrous metal, but its considered as a highly toxic element in drinking water at high concentration and the trace aluminum content in food must be controlled. This paper shows effective removal of aluminum from water and industrial wastewater by magnetic nanoparticle. The method is fast, simple, cheap, effective and safe for treatment of aluminum polluted waters. Preparation of adsorbent is easy and removal time is short. magnetic iron oxide nanoparticles (MIONPs) can adsorb up to 99.8% of 60 ng ml-1of Al ions from polluted water. The required time for complete removal of aluminum ions was 3 minutes. Variation of pH and high electrolyte concentration (NaCl) of the solution do not have considerable effect on the aluminum removal efficiency.
