Comparison of the efficiency of ultraviolet/ultrasonic (UV/US) and ultraviolet/zinc oxide (UV/ZnO) technologies as advanced oxidation processes in the removal of linear alkylbenzene sulfonate (LAS), an anionic detergent, from aqueous media

Surfactants are one of the most commonly found xenobiotics in municipal and industrial wastewater. The purpose of this study was to compare ultraviolet/ultrasonic (UV/US) and ultraviolet/zinc oxide (UV/ZnO) processes in the removal of LAS from aqueous media.In this study, a medium-pressure UV lamp (...
