Heterogeneous Photocatalytic Degradation of Azure-A Dye By Highly Efficient Zno-Nano Photocatalyst In Presence Of Different Operational Parameters
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 3
Abstract
Nowadays, environmental pollution is a critical problem of the world. In this paper, we report the successful synthesis of ZnO Nano photo catalyst by the precipitation method and their effective use as a photocatalyst for photo catalytic degradation of organic dye using safe and inexpensive visible light. Photo catalytic heterogeneous degradation is most effective method of purification of polluted water. Textile wastewater includes a large variety of dyes and chemicals additions that more the environmental challenge for textile industry not only as liquid waste but also in its chemical composition. Advanced oxidation processes hold great promise to provide alternative for better treatment and protection of environment pollution, in this paper the effect of different operational parameters such as, catalyst loading, initial dye concentration, pH variation, H2O2 and K2S2O8 oxidants and effect of other commercial photo catalyst on the extent of Heterogeneous photo catalytic degradation rate have been investigated.
