Sonolysis of Aqueous Solutions under Argon: Dependence of the Rate of Hydrogen Peroxide Formation on Hydroxyl Radical Scavenger Concentration

The dependence of the rate of formation of hydrogen peroxide on ^·OH radical scavenger concentration in aqueous solutions exposed to ultrasonic irradiation under an argon atmosphere has been investigated, and it is shown that for the scavengers used (methanol, ethanol and acetate ion) the rate decreases directly with the cube root of the scavenger concentration, analogously to the dependence observed in the radiolysis
