Deskripsi
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 <sup>90</sup>Sr, <sup>90</sup>Y, and (UO<sub>2)</sub><sup>2+</sup>. The new material shows excellent retention for (UO<sub>2</sub>)<sup>2+</sup>, 97%; these values were 73% and 100% for <sup>90</sup>Sr and <sup>90</sup>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.
