Abstract

The removal and recovery of Uranium from aqueous media has been considered by many scientists and researchers since a long time ago. In this work it has been tried to produce the nano adsorbent that can separate the Uranium from nuclear waste waters and the other aqueous media. For this purpose poly(styrene-acrylonitrile) Nanofibers and their composite with polycarbonate Nanofibers have been prepared and used as adsorbent of Uranium after the chemical modification. The chemical modification was performed by the conversion of nitrile groups to amidoxime groups by hydroxyl amine solution and akaline treatment by sodium hydroxide 2. 5%. The amidoximation was confirmed by the infrared spectroscopy. The maximum capacities of Uranium adsorption were 79. 8 and 38. 5 mg U/g ads for poly(styrene-acrylonitrile) and poly(styrene-acrylonitrile)/polycarbonate composite, respectively. The optimum pH was 4 for Uranium adsorption. The desorption yield was more than 90% in Na2CO3 1M/H2O2 1M solution.
