Concentration of hydroxyl radicals in the interfacial regions of cavitation bubbles
Shin-ichi Hatanaka (Univ. of Electro-Comm.) US2011-103
Abstract (in Japanese) (See Japanese page) 
(in English) A local concentration of the OH radicals in the interfacial regions between the cavitation bubbles and the liquid is derived from the production rate of hydrogen peroxide and iodine in aqueous potassium iodide solutions. The products of hydrogen peroxide and iodine result from the competitive reactions of the OH・+ OH・and the OH・+ I－, respectively, because the total yield of the products is independent of solute concentration. At 650 kHz ultrasonic irradiation, 2 mM was obtained for the concentration of the OH radicals in the interfacial region, which was 2 orders of magnitude higher than the concentration in the bulk liquid.
