One-Pot Environmentally Friendly Synthesis of Nanomaterials Based on Phytate-Coated FeO Nanoparticles for Efficient Removal of the Radioactive Metal Ions Sr, Y and (UO) from Water.

We report the fast (three minutes) synthesis of green nanoparticles based on nanoparticles coated with the natural organic receptor phytate for the recognition and capture of Sr, Y, and (UO. The new material shows excellent retention for (UO), 97%; these values were 73% and 100% for Sr and Y, respectively. Recovery of the three radioactive metal ions occurs through a non-competitive process. The new hybrid material is harmless, easy to prepare, and immobilizes these radioactive contaminants in water with great efficiency.
