摘要
Ultrasonic impact on natural waters was applied to identify hydrochemical anomalies from the changes in the characteristics of sonoluminescence generated by ultrasonic cavitation in a flowing water sample. Sonoluminescence excitation spectra characteristic for various natural water pollutants were obtained for the first time. The suitability of changes in the sonoluminescence intensity and in the shape of the sonoluminescence excitation spectra as indicators of hydrochemical anomalies was elucidated.
