Sonoluminescence with a specific wavelength emitted from the cavitation bubble produced by a sufficient acoustic energy irradiated into the liquid solution. The specific wavelength depends on the element in water solution. In this paper, as a fundamental study on sonoluminescence for elemental analysis, strontium sonoluminescence characteristics of different parameters were investigated. The experiment was conducted with 3 working frequencies (26, 78 and 137 kHz) in the power range from 0-50 W in 4 different concentrations of strontium (0.05 M – 3 M). The results were analyzed using MATLAB code for image processing with HSV based color identification technique. As the final results in the form of a percentage of sonoluminescence relative intensity show that higher sonoluminescence intensity emitted at higher ultrasound frequency, highest sonoluminescence intensity emitted at highest ultrasound power and higher intensity emitted at higher solution concentration. In addition, the HSV technique can be used for analyzing the sonoluminescence relative intensity for elemental analysis.
