Resumen
Industrial wastewater are discharged from industrial plants and manufacturing process. Water polluted by heavy metal is one of the serious environment problems. Various methods for remove this metal ions from the water have extensively been studied. Usage of magnetic iron oxide nanoparticles (MNPs) based nanomaterials to treat water from heavy metals is well-known adsorbents for remediation of water. Due to its important physiochemical property, cheap method and easy regeneration in the existence of external magnetic field make them more attractive toward water purification. The aim of this study is the preparation of magnetic iron oxide nanoparticles and coating it surface with glycine to increases the efficiency of MNPs for the removal of the Cu2+ ion from the aqueous system. Microemulsion method used to prepare bare magnetic iron oxide nanoparticles using Iron (III) Chloride Hexahydrate and Iron (II) Chloride Tetrahydrate in presence of ammonium hydroxide. Different instrumental analysis such as FTIR, XRD and SEM used to study the magnetic iron oxide nanoparticles that produced and comparing it after coated with glycine. The Atomic absorption spectroscopy (AAS) used to analyze the percentage removal of Cu2+ ion from aqueous solution. The parameters studied in this study were effect of different dosage of nanoparticles and effect of different pH solution. The results show the optimum parameters which reflect the high efficiency of removal, which is more than 98%, are pH 9 and 0.05 g of dosage by using Magnetic iron oxide nanoparticles that coated with glycine.
