| Research Abstract |
Liquid-surface vibration amplitude and the intensity of sonochemiluminescence(SCL) with luminol were detected. It was found that the SCL intensity increases and reaches its peak and after that decreases with the applied power. The vibration amplitude of liquid surface was the order of 100 ms. It has been clarified that the amplitude more than 1/4 of sound wavelength is responsible for destruction of stable resonant standing wave structure effective for sonochemical reaction and, accordingly, the reduction in efficiency in the reaction at excess sound pressure amplitude comes from liquid surface vibration on a sonochemical reactor.
