Abstract

This paper studies the environmental application of AOPs in treating dye wastewater. The azure B dye has been chosen as a pollutant. Photocatalytic degradation of azure B by nanoBiOCl was studied under solar light. BiOCl was prepared by a simple method and characterized by by XRD and SEM. XRD pattern suggested that the synthesized nano BiOCl was highly pure and crystalline, SEM images depicted the platelike morphology of nanoBiOCl. The average particle size of nanoBiOCl was obtained as 45 nm. The photocatalytic studies have revealed that optimum pH was 8, initial dye concentration was 4.0 ×10-5mol L-1, catalyst loading was 30 mg/100 ml of dye solution. The optimum concentrations of electron scavengers and salts have also been obtained.
