Ionic surfactant accumnlates at the gas-liquid interface of cavity because of their amphipathicity and extremely low vapor pressure, it is difficult to diffuse into the interior of the gas phase region of cavity. On the basis of this property, the sonolysis of the ionic surfactant supposed to be occurred at interfacial region of cavity. In this research, ionic surfactants with different carbon chain lengths were ultrasonically decomposed and the decomposition rate and the amount of gaseous hydrocarbons produced were compared in order to elucidate the molecular behavior and reaction in the interface region of cavity. The effect of the surface potential of cavity on the sonolysis of surfactants was also investigated.
