Solar Active Reusable Photocatalyst Magnetite Doped Calcium Aluminate for Acid Yellow 23 Photodegradation

Abstract

Fe3O4 doped calcium aluminate nanoparticles were synthesized by co-precipitation method, an effective route to synthesize novel photocatalyst to enhance the photocatalytic decolourization of acid yellow 23 dye. The structural and surface morphologies were investigated using techniques such as SEM and EDAX. In this study, a degradation of acid yellow 23 dye have been carried out in the presence of sunlight. It was observed that the synthesized Fe3O4 doped calcium aluminate photo catalyst was very useful in degrading the dye entirely within a short span of time (90 min). The impact of various operating parameters on acid yellow 23 including the amount of photocatalyst, dye concentration, H2O2 concentration and temperature was thoroughly examined. The kinetic studies explained that the degradation of photocatalytic reaction showed pseudo first-order reaction.
