摘要：
A synergetic effect is found in the sonochemical formation of HNO2 in HNO3 solution in the presence of an N2O–Ar gaseous mixture. The maximum rate of HNO2 formation is observed at an N2O : Ar ratio of 15 : 85 (v/v). During the sonolysis of 4 M HNO3 solutions, the rate of HNO2 formation increases multifold due to the synergetic effect. The rate of sonochemical hydrazine decomposition in nitrate solutions also increases considerably in the presence of N2O.
