Ameerah S. Jawad and Hazim Y. Al-gubury

Abstract

Photocatalytic-degradation process of Safranin-T dye in this article has been investigated by using prepared nanocomposite and solar lamp. Zinc oxide/vanadium pentoxide nanocomposite was prepared using “hydrothermal processes”. The degradation of dye was performed by irradiated aqueous suspended solutions containing different concentrations of dye using 0.2g/100ml of nanocomposite. The effect of various factors on the photocatalytic-degradation process of Safranin-T dye was tested to reach an optimal state, where they involve the effect of the nanocomposite mass and the effect of Safranin-T dye concentration the effect of light intensity and effect of temperature. The activation energy has been calculated equal 28.84 kJ.mole-1 The irradiated solutions were studied using UV-Vis spectrophotometer.
