Summary:Title screen
Magnetically separable adsorbents with high sorption capacity for (UO2)2+ ions have been successfully synthesized on the basis of fungus–Fe3O4 nanoparticle bio-nanocomposites through a simple co-culture method. Fungus–functionalized Fe3O4 nanoparticles pave the way for highly efficient separation of the adsorbents from contaminated water without altering the large specific surface area of fungus. The bio-nanocomposites with high dispersibility of Fe3O4 nanoparticles are uniformly distributed on the macro-scale fungus carrier that weakens the aggregation of nanomaterials, thus improving the sorption capacity. Furthermore, this adsorbent with high biological activity can effectively and specifically adsorb radioactive ions in water with saturated sorption capacity up to 171 mg/g for (UO2)2+ ions. The fast adsorption process can guarantee that the radioactive ions will be removed within only four hours. Our results indicate that the bio-nanocomposites can be used as a cost-effective adsorbent for removing radioactive ions from wastewater.
