PREPARATION AND IDENTIFICATION OF FE (III) NANOOXIDE USING FIG LEAF (FICUS LYRATA) EXTRACT AND STUDY OF ITS EFFECT ON THE PHOTOSYNTHESIS OF POLY (VINYL ALCOHOL).

The study involved preparing (Fe₂O_3NPS) green method using fig leaf (ficus lyrata) extract, diagnosing it and studying its effect on the photovoltaic properties of polyvinyl alcohol prepared by casting and 65±5μm thickness after adding concentrations of nanomaterial (0.0025, 0.005, 0.01, 0.02, and 0.04) % to the polymer solution before and after exposure to the UV source at wavelength (356) nm and irradiation bazaan (0, 10,20, 40 and 80) hrs. The resulting iron oxide (Fe₂O_3NPS) was diagnosed using X-ray diffraction (XRD) and Atomic Force Microscope (AFM), which showed the size of the minutes (19.9) Nanometer and scanning electron microscope (SEM), irradiation on polymer chips were followed by Uv-vis spectrometer (UVVisble for calculating the dissociation constant (K_d) as well as using (FT-IR) to calculate the growth of the hydroxyl group coefficient (I_OH) and the growth of the carbonyl coefficient (I_CO). As well as calculating the molar mass of the polymer, the degree of dissociation (á), and the numerical rate of the polymer chain cut-off (S) using the viscostometer. The speed of photosynthesis and the decrease in the rate of visual molecular weight is directly proportional to the added iron oxide concentration and irradiation time, consistent with what surface morphology has shown.
