Study of the Effect of Ultrasonic Radiation on Aqueous Solutions of Potassium Iodide

It has been established for the first time that an aqueous solution of potassium iodide releases molecular iodine under the action of ultrasound radiation when cavitation occurs. The process of iodine release occurs in an oscillatory mode. It has been shown that the rate of iodine release and its maximum concentration depend on the ultrasound intensity, the concentration of the potassium iodide solution and the ultrasound frequency. At the same time, an increase in the concentration of potassium iodide in the initial solution above 5–6% does not lead to a further increase in the concentration of the iodine formed. The dependence of the maximum iodine concentration on the oscillation amplitude of the waveguide end is nonlinear.
