Method for comparing the efficiency of ultrasound irradiation independent of the shape and the volume of the reaction vessel in sonochemical experiments

The method described herein this review compares the efficiency of ultrasound irradiation in sonochemical experiments in organic solvents. This method was shown to be independent of the shape and volume of the reaction vessel. The principle of this method is based on the fact that the concentration of dissolved oxygen in the entire reaction volume during acoustic cavitation depends on the ultrasound power or intensity of ultrasound field respectively. The concentration of dissolved oxygen is determined by the measurement of the fluorescence intensity with fluorescence probes.
