Removal of heavy metals from medical wastewater by using green synthesis FeO nanoparticles and resin

Mohammed Kudair Mohammed, Raghad Mukdad Mahmoud

Abstract

Heavy metals are considered one of the most dangerous pollutants. They are known as metallic elements with a high atomic weight: lead (Pb), cadmium (Cd), iron (Fe), chromium (Cr), copper (Cu), zinc (Zn), manganese (Mn), and nickel. (Ni) and silver (Ag) which may harm organisms in low concentrations and which accumulate in the food chain. This study aims to removal heavy metal from medical wastewater by using green FeO nanoparticles synthesis and resin. The results appeared the smallest crystal size by X-ray diffractometer was 16.58nm for FeO green synthesis with Punica granatum . The surface morphology of green FeO NPs appeared by using AFM, the average grain size was 40.139 nm and the nanoparticles were almost spherical. The outcomes of treatment the physical and chemical factors, heavy metals and bacterial growth was found that the column of resins with green synthesis FeO nanoparticles , the column showed a high removal rate of heavy metals (99.8-99.9%),also calcium(98.6%) ,magnesium(98.7%), total hardness(98.7%), total suspended solids(93.1%), total dissolved solids(99.3%), turbidity(81.2%) and conductivity(99.1%). It was concluded in the current study efficiency FeO nanoparticles green synthesis with aqueous extract of Punica granatum in treatment of wastewater and increasing the efficiency resin in treatment.
