摘要：

The iron oxide magnetic nanoparticles (MNPs) have been synthesized by using a co- precipitation method aqueous solution of ferric and ferrous ions in, sodium salt, which is used to controlled The size of the iron-oxide, then coated those nanoparticles with different weight ratio of dextrin. The samples were characterized by x-ray diffractometer (XRD), FTIR spectroscopy, atomic force microscope (AFM) and scanning electron microscope (SEM).The research studied the ability of using coated magnetite with weight ratio of dextrin(1-2) as adsorbents for the removal of heavy metals like lead and chrome from aqueous solution with in variable experimental factors. The data obtained from this study revealed that higher efficiency was observed with lead ion whereas the lower with chrome ion. (C) 2019 The Authors. Published by Elsevier Ltd.
