P27 超音波キャビテーションバブル界面における陽イオン界面活性剤の分解

抄録

Sonolysis of cationic surfactant, alkylbenzene ammonium salt (BAC) with different carbon chain length was investigated to analyze the reaction at the interface of cavitation bubbles. BACs accumulate at the gas-liquid interface of cavitation bubbles but do not go into the bubbles because of their involatile and amphiphilic properties. We also compared the sonochemical degradation rate of cation surfactant with that of anion surfactant previously reported.The surface potential of cavitaion bubbles was discussed on the basis of relation between initial surfactant concentration and thier critical micelle concentration.
