【摘要】 本文对水(十六烷基三甲基溴化铵,CTAB)/硝基甲烷(苦味酸)/水(葡萄糖)体系的液膜振荡进行研究。应用电势线性扫描法通过测定界面电压变化研究了开放体系与封闭体系的液膜振荡并进行了对比,对开放体系还研究了不同滴定速度对液膜振荡的影响。根据J.Srividhya和M.S.Gopinathan的数学模型,对开放体系的振荡进行了相应的数学分析与求解。结果表明:开放体系比封闭体系振荡频率高,振幅小;随着滴定速度增大,振荡频率增高,振幅减小;通过数学模型的计算得出的图谱与实验中振荡图谱有一定的相似性,定性上相吻合。更多还原

【Abstract】 The liquid membrane oscillation of a water(CTAB)/nitrobenzene(Picric acid)/water(Glucose)system was investigated.The liquid membrane oscillation of the open/closed systems was measured by recording the interface voltage change with a homemade device.The liquid membrane oscillation of the open system was analyzed according to the mathematical model of J.Srividhya and M.S.Gopinathan.The results show that there is higher oscillation frequency and lower amplitude in the open system.The oscillation frequency increases and amplitude decreases with an increase of the titration speed.The experimental oscillation agrees well with simulation oscillation.更多还原
