Formation of nitric ion during ultrasonic irradiation was examined under various conditions. Source of oxidation power in sonolysis is acoustic cavitation. The cavitation occurs in a liquid irradiated with ultrasound. Some kinds of active species are produced during cavitation. Radicals and hydrogen peroxide are typical oxidizing agents in noble gases or oxygen. In the air, on the other hand, nitric acid is also produced when sonolysis is carried out in an aqueous solution. It plays an important role in oxidation. It is not saying, nitric acid or nitric ions are also useful in organic reaction, mainly synthesis. To increase yield of nitrate ion, we irradiate pulsed waves of ultrasound. In this presentation, effects of rest time of irradiation and atmospheric gas on yield of nitric ion were reported.
