Application of magnetic polyaniline nanocomposite for separation of uranyl ions from aqueous solutions
Polyaniline (PANI) was synthesized chemically, and then modified with magnetic iron oxide nanoparticles (Fe 3 O 4 NPs). PANI and PANI-Fe 3 O 4 NPs were used for removal of uranyl ions (UO 2 2+ ) from aqueous solutions using a batch system. The synthesized adsorbents were characterized using FT-IR, S...
