We have performed a fundamental research about sonoluminesence of water. Firstly， effect of dissolved chemical compounds such as inorganic sa1ts， f1uorescent dyes， and chlorinated organic solvents in water on the sonoluminesence were studied with a home-made expermenta1 setup. Results shown that the sonoluminesence was enhanced greatly by the chlorinated organic solvents. Secondly， hydrogen peroxide in the water solutions after irradiation of ultrasonic wave was measured with a chemi1uminescence method using luminol. Experimental results shown that the amount of hydrogen peroxide was icreased in water solutions containing the chlorinated organic solvents after the irradiation. Final1y， ion chromatography was used to analyze ultrasonic wave-irradiated water solutions containing chlorinated organic solvents. Experimenta1 results shown the existence of chloride ion in the ultrasonic wave-irradiated water solutions， which is produced by the decomposition of the chlorinated organic solvents.
