The sonochemical efficiency of a cylindrical sonochemical reactor has been investigated as a function of frequency and liquid height. The irradiation frequencies were 45, 129, 231 and 490 kHz. The liquid height was varied from 10 to 700 mm. The sonochemical efficiency of the cylindrical reactor was evaluated by potassium iodide (KI) dosimetry and calorimetry. In our study, the sonochemical efficiency depended on the frequency and liquid height; further, the plots of sonochemical efficiency against liquid height exhibit one or two peaks for each frequency. The sonochemical efficiency up to the first peak increased monotonically with the logarithm of the frequency, and the liquid height for the first peak was inversely proportional to the frequency. From these results, the optimum frequency for a sonochemical reactor can be determined if the liquid height is specified for scale-up of the sonochemical reactor.
已研究了圆柱形声化学反应器的声化学效率与频率和液体高度的函数关系。辐照频率为45、129、231和490千赫兹。液体高度在10至700毫米之间变化。通过碘化钾（KI）剂量测定法和量热法评估圆柱形反应器的声化学效率。在我们的研究中，声化学效率取决于频率和液体高度；此外，声化学效率相对于液体高度的曲线在每个频率下都呈现一个或两个峰值。直至第一个峰值的声化学效率随频率的对数单调增加，且第一个峰值对应的液体高度与频率成反比。根据这些结果，如果为声化学反应器的放大指定了液体高度，就可以确定声化学反应器的最佳频率。
