عنوان انگلیسی Photocatalytic Degradation of Fast Green Dye Using Nickel Oxide Nanoparticles for Removal Industrial and Environmental Pollutants
چکیده انگلیسی مقاله The increasing requirements for paints and chemicals in industry have necessitated the use of several techniques to reduce pollution, including a combined chemical precipitation(Co-precipitate) approach to prepare NiO nanoparticles in the form of NPs nanoparticles, where structural and morphological analyzes revealed the formation of nanostructures, such as the scattering of X-rays (XRD) , Fourier transform Infrared spectroscopy(FTIR) a technique used to analyze the interaction between matter and infrared radiation by measuring the absorption, emission, or reflection of infrared light, and dispersive energy X-ray spectroscopy (EDX) analytical techniques used in scientific research, , Electron scanning microscopy ,and Thermal gravimetric analysis (TGA). The second part includes the study of the photo catalytic activity of prepared nanocomposite, using a fast green dye. The rate of the photocatalytic degradation process was affected by different parameters such as the concentration of dye, effect of a mass of catalyst, and the effect of temperature. The experiments were performed under optimum conditions from (0.15 g / 100 mL) of NiO nanocomposite, with an air Rate of flow of 10 mL/min. The best removal amount of Fast green dye was (91.45%). The effect of dye concentration has been used to study the optimum value of Fast green dye (10mg/L) dye. The activation energy for the photo degradation process calculated using the Arrhenius equation was equal to (31.67. ±1 kJ.mol-1).
