Research Abstract	The rigorous evaluation method for the formation rate of hydroxyl radical by titanium dioxide catalyst under the ultrasonic irradiation has been constructed. At first, the formation rate of hydroxyl radical in the absence of titanium dioxide was evaluated by using a kinetic model for the reaction between spin label species and hydroxyl radical. Then, the formation rate of hydroxyl radical in the presence of titanium dioxide was evaluated by using a kinetic model considering the adsorption of spin label species onto titanium dioxide.
