【Abstract】 The enhancement of sonochemical yield by combining orthoganal ultrasonic irradiation at 28 kHz and 0.87 MHz frequencies has been firstly studied by means of Iodine Release method in this paper.The experimental results have shown that the sonochemical yield produced by the combining irradiation appears to be remarkably larger than the sum of the yilds produced separately by the two single irradiation.更多还原
