摘要：

A new in-situ magnetite nanoparticles inserted into crosslinked poly (acrylamido-amineamidoxime-co-2-acrylamido-2-methylpropane sulfonic acid (AO/AMPS) were prepared and used as novel uranium adsorbents. The prepared composites were applied as adsorbents to remove U(VI) from aqueous solutions that could be separated by a simple magnetic separation method. The removal of U(VI) was evaluated by spectrophotometric method using arsenazo-Ill as complexing agent. The results showed that, the sorption process strongly depended on pH and the sorption equilibrium can be reached within 150 min. The Langmuir sorption isotherm model correlated well with the uranium sorption equilibrium data for the concentration range of 50-500 mg/L.
