This research aims at exploring possible application of the sonoluminescence phenomenon to water analysis. Experimental setups for measurement of sonoluminescence of water or sonic chemiluminescence of luminol aqueous solution have been prepared. Firstly an ultrasonic cleaner was used as a source of sonic wave. A glass tube used as a cell was directly immersed into water in the cleaner. Sonoluminescence of water from the cell was detected by a photomultiplier tube (PMT) . Although sonoluminescence of water was very weak, sonic chemiluminescence of luminol solution was strong enough in the ultrasonic cleaner. Secondly, an ultrasonic homogenizer was used as the sonic wave source. A micro tip of the ultrasonic homogenizer was directly immersed into a cell, which was a glass tube with internal diameter of I cm. Strong and stable sonoluminescence of water was observed. Experimental factors affecting the sonic chemiluminescence of luminol and sonoluminescence of water have been examined. The potential application of the sonoluminescence was also discussed.
