摘    要:本文用碘释放法研究了28kHz超声的声化学产额随扬强和辐照时间的变化。表明声化学产额随声强呈非线性变化,而随辐照时间近似呈线性变化。进而研究了由28kHz与1.06MHz组成的正交辐照系统的声化学产额。

Abstract:The dependence of sonochemical yield produced by 28kHz ultrasound on sound intensity and sonication time has been studied by using iodine release method in this paper. It has been shown that the sonochemical yield varies nonlinearly with sound intensity and linearly with sonication time. We have further studied the sonochemical yield by a combining orthogonal ultrasonic irradiation system at frequencies of 28kHz and 1.06MHz. It is shown that the sonochemical yield produced by the bifrequency irradiation appears to be much more than the sum of yields produced separately by the two irradiations. This result has provided a heartening prospect for the development of sonochemical technology.
Keywords:sonochemistry  ultrasound cavitation  iodine release
