Effect of carbon tetrachloride on the luminol sonochemiluminescence reaction kinetics during multibubble cavitation

•The presence of CCl4 allows following the luminol sonochemiluminescence in real time using a cell phone video camera.•The nature of the ions and the ionic strength affect the kinetics of the luminol sonochemiluminescence.•Ethanol quenches the luminol sonochemiluminescence in the presence of CCl4. The sonochemiluminescence (SCL) of luminol reaction was studied in alkaline medium using a dissolution of luminol, sodium carbonate, hydrogen peroxide and carbon tetrachloride. The presence of carbon tetrachloride enhances the SCL reaction up to allow the study of the reaction in real time using a cell phone video camera. This experimental setup allows the study of the cavitation dynamics in real time and through all the reactor, including homogeneous and heterogeneous cavitation zones. Finally, it was tested the effect of ethanol, the ionic strength and pH on the SCL.
