In order to investigate the region of effective chemical reaction field in a sonoreactor, the power input per unit volume of liquid and the liquid height were varied. Decolorization experiments using iodine and disodium hydrogenphosphate in a starch solution under chemical reaction rate control conditions were carried out and the effect of ultrasonic irradiation on the chemical reaction was examined. The region of the effective chemical reaction field depended on the power input per unit volume dissipated in the liquid but did not depend on the liquid height. With increasing the power input per unit volume of the liquid, the region of the effective chemical reaction field became larger and the effective chemical reaction rate increased.
