Preparation and Characterization of a Surface Modified Amberlite IRA 402 Resin by Nano Iron Oxide and its Application for Uranium Separation

Sadeek Sadeek, Mohammed Galal, Mohammed shiera, Mahmoud Ramadan, Mohammed Ramadan


A nano-iron oxide modified Amberlite IRA402 resin was prepared by the reaction of iron(II) and iron(III) ions in the presence of ammonium solution. The modified resin has been characterized by transmission electron microscopy, FTIR, X-ray diffraction, and scanning electron microscope images. In a batch experiments, uranium adsorption was evaluated using the modified Amberlite resin. The adsorption parameters studied were pH, contact time and the sorbent amount. The maximum adsorption capacity of the modified resin for uranium was 267.85 mg/g. Finally, modified Amberlite IRA-402 could be successfully used for separation of uranium from Sinai claystone leach liquor more than Amberlite IRA-402 without any modification.
