Nowadays ultrasound has been successfully used to degrade the organic pollutants in wastewater. It has many advantages in toxic and no biodegradable organic waste water treatment either as the independent operation unit or in combination with other treatment methods. The degradation of levofloxacin in aqueous solution as the simulant organic pollutants by ultrasonic irradiation was studied in this paper. A pulsing sonifer with a frequency at 20 kHz was used to study the sonochemical technology. The work was...
