英文摘要Ternary magnetic composites of poly(acrylamide)-stabilized FeS/Fe3O4 (denoted as PAAM-FeS/Fe3O4) were in situ synthesized by chemical coprecipitation of FeS/Fe3O4 in the presence of acrylamide (AAM), followed by dielectric barrier discharge (DBD) plasma-induced polymerization of AAM on the FeS/Fe3O4 surface. The modified PAAM improved greatly the stabilization and dispersion properties of PAAM-FeS/Fe3O4 in aqueous solutions. This as-prepared composite was applied as an adsorbent for the preconcentration of U(VI) cations from aqueous solutions. The maximum enrichment capacity of U(VI) on this adsorbent at pH 5.0 and 20 degrees C was calculated to be 311 mg g(-1). The presence of other cations had no obvious influence on the sorption of U(VI) on PAAM-FeS/Fe3O4, suggesting that this absorbent can remove U(VI) with high selectivity. According to the results of XPS spectra analysis, both FeS and amide groups on PAAM-FeS/Fe3O4 surfaces have strong chemical affinities to U(VI), and FeS can also reduce U(VI) to U(IV) effectively. The coagulation of magnetic U-laden PAAM-FeS/Fe3O4 can be easily separated and recovered from aqueous solution by simple magnet separation. This paper highlights the potential application of PAAM-FeS/Fe3O4 composites as suitable materials for the preconcentration and extraction of trace U(VI) ions from aqueous solutions in environmental radioactive pollution control and peaceful utilization of nuclear energy, such as the extraction of trace U(VI) ions from seawater.
