Abstract

Long time single bubble sonoluminescence as long as thirty hours was achieved by suppression of amount of the dissolved oxygen. Under this condition, formation of nitric and nitrous acid from the single bubble was observed. The ratio of production of nitric to nitrous acid was 1:1 and the amount of the acids is 8×lO^<-7> mol・dm^<-3> under the sonication of thirty hours. The amount of formation both acids linearly increased with increasing in sonication time. Amount of formation for aqueous solution of methanol of 2.6×10^<-4> mol・dm^<-3> is about a half of those for water. The intensity of the sonoluminescence of the aqueous solution of methanol was a half of that of water. This fact implies that the amount of formation is affected by the temperature in the bubble. One of the possible reaction scheme for the formation of nitric and nitrous acid is written as follows, N_2 → 2N・ (1) NO+O・ → NQ (5) O_2 → 2O・ (2) NO+OH・→ HNQ (6) H_2O → H・+ OH・ (3) NO+OH・+O・ → HNO_3 (7) N・+O・→ NO (4) 2NO_2+H_2O → HNO_2+HNO_3 (8) If the reactions (5), (6) and (7) proceed with the same probability, the equal amount of nitric and nitrous acid is produced.
