Removal of 2-mercaptobenzoxazole from water as model of odorous mercaptan compounds by a heterogenous photocatalytic process using Ag-ZnO nanocomposite coated thin film on glass plate.
A photocatalytic process was evaluated for the removal of 2-Mercaptobenzoxazole (MBO) in wastewater. More than 90% of the MBO was removed by photocatalytic oxidation at about 3 h of irradiation time using Ag-ZnO nanocomposite thin film catalysts coated on glass by dip-coating. Ag-ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM). The initial concentration of MBO was 20 ppm with optimum pH value of about 8.0. This investigation will give a new insight to understanding the mercaptan photodegradation in aquatic environment.
