Synthesis of new Adsorption System Contain Iron-Hay-Nano Product and their Application for Removing Some the heavy Metals from Polluted Waters

Abstract

Iron nanoparticles were synthesized by wet method. The reaction was done using iron salts as a source of iron, glucose was used as a reducing agent and trisodium citrate was used as a capping agent. The synthesized iron nanoparticles were added to hay powder in order to increase the desorption efficiency of hay. A new adsorption system contains iron nanoparticles–Hay was applied for removal of cadmium from polluted waters. The formation of iron nanoparticles was monitored using sevral instruments; UV-Vis spectra showed iron nanoparticles formation by exhibiting the characteristic surface plasmon absorption maximum at 350 nm. Transmission electron microscope (TEM) and scanning electron microscope (SEM) were used to identify the size and the morphology of iron nanoparticles. The images indicate that the synthesis of iron nanoparticles were in the range of 15-80 nm and were spherical in shape. The synthesized iron nanoparticles were applied for removal of heavy metals such as cadmium from polluted waters and flame atomic absorption spectroscopy (FAAS) was used for determination of the concentrations of cadmium before and after the addition of iron nanoparticles.
