Abstract:- Cadmium is one of the toxic elements, used in many industries. It is antoxic heavymetal that affects living organism cadmium can be removed from water by adsorption, chemicalprecipitation, ion exchange, reverse osmosis, electrochemical treatments. Due to low cost-effective, high efficiency, adsorption technology is regarded as the most promising one to remove heavy metal ion from other techniques nanoscale iron oxides have become raw material for treating the waste waters and soils. Fe₂O₃ magnetic nanoparticles adsorbs Cadmium (II) this experiment was studied by Batch adsorption method Percentage adsorption decrease as pH of solution increases. The adsorption is maximumat 5 pH and then it is decreases. Percentage adsorption decrease as metal ion concentration increases. The adsorption is maximum up to 200 µg/ml and then it is decreases. Percentage adsorption decrease as metal ion concentration increases. The adsorption is maximum at 50 µg/ml. The 10 min. contact  time is sufficient for maximum adsorption of Cd (II) particles  The present study shows MNP's can be used as an inexpensive sorbent for the sorption of Cd⁺²   from aqueous solution. Thus, this work provides an alternative adsorbent for cadmium removal from aqueous solution.
