Abstract

Energy characterization of a pulsed ultrasonic system was carried out using a modified calorimetric method. Sonochemical efficiency (SE) for the oxidation of Fe+2 and the formation of H2O2 was determined for selected on:off ratios (R) and different power levels. The measured efficiency of the pulsed ultrasonic system of 60-70% in converting electrical energy into calorimetric energy was found to be constant for all Rratios and equivalent to that for continuous operation. SE of Fe+2 and H2O2 for pulsed ultrasound was higher than that of continuous ultrasound. The ratio R=0.2:0.1 had the highest SE values overall, while for long off-timeratios,R=0.1:0.6 recorded the highest value of SE. These results were supported by the production rates results for Fe+2 and H2O2.
