Using of iron oxide nanoparticles and application in the removing of heavy metals from sewage water

Abstract EN

This study investigated the applicability of iron oxide (Fe2O3) nanoparticles for the removal of cadmium metal from sewage water by using batch scale experiments.

The iron oxide nanoparticles of 27.7nm were synthesized using a biological method and characterized by Atomic Force Microscope (AFM).

The Box-Wilson design was used to conduct experiments with three parameters such as pH (2-6), time of adsorption (6-120min) and adsorbent dosage (5-25mg/L).

The best conditions occurred at pH: 5.5; contact time: 95.8 min; and iron oxide nanoparticle dosage: 20.77 mg/L for maximum cadmium removal of (96.9%).
