Photocatalytic Degradation Study of Coralene Blue BGFS Azo Dye by Using Synthesized SrAl2O4 Nanoparticles and UV Light

Abstract

Photocatalysis is an emerging method in dye degradation in wastewater treatment, which provides an alternative for energy saving technique by using renewable solar energy and UV light. The SrAl₂O₄ nanoparticle as photocatalyst was synthesized by solution combustion method with acetamide as fuel. These nanoparticles were characterized by XRD, SEM, and UV-absorption spectroscopy. Under artificial UV light, the photocatalytic activity of the synthesized nanoparticles was employed to degrade Coralene Blue BGFS azo dye by altering parameters such as dye pH, dye concentration, and catalyst concentration. The maximum photocatalytic degradation of Coralene Blue BGFS was recorded 84.27% at acidic condition (pH 4).
