Abstract :
Introduction: Various absorbents have been studied for removing heavy metals from water. One of the most effective removals is iron oxide nanoparticles. In recent years many studies have been carried out for modifying the surface of the nanoparticles and increasing its effectiveness and efficiency. Materials and Methods: In this paper coated iron oxide nanoparticles were prepared using Polylophium involucratum extract. To examine the structure of the absorbent the infrared spectrometer instrument and SEM were used to check the size of nanoparticles. the average size of them were determined 60 nm. Results: The synthesized coated nanoparticles were used to eliminate lead and cadmium after optimization conditions (pH of 6, absorbent weight of 20 mg, and time of 4 minutes) in water samples. Magnetic green coated nanoparticles have many advantages such as non-toxicity, biocompatibility, shorter extraction time, avoiding the use of organic solvents, low cost, ease of use, high accuracy, recovery and adsorption capacity due to the nanostructure and high ratio of surface to volume. Conclusion: Functionalized nanoparticles by extract of the plant is able to link up with heavy metal ions and increase the efficiency of the nanoparticles in the removal of these two heavy metals.
