 In this study, three types of nanoparticles, FE-203, CUO, and ZNO, were synthesized using a plant extract from Portulaca oloracea leaves. The particles were characterized with UVVIS spectrophotometry, for ear-transform infrared spectroscopy, FTIR, X-ray diffraction, XRD, scanning electron microscopy, SEM, and energy dispersive spectroscopy, EDS. The particles were tested for their ability to remove various heavy metals and pollutants from wastewater, including arsenic, AS-3, bismuth, Bi-2, cadmium, CD-2, chromium, CR-6, manganese, MN-2, molybdenum, MO-2, nickel, Ni-2, lead, PB-2, antimony, Sb-3, selenium, Se-2, and zinc, ZN-2. The results showed that all three nanoparticles had high efficiency in removing the targeted heavy metals and pollutants from wastewater.
