摘要：

用循环线性电流扫描计时电位法和循环伏安法研究了双1∶11镝的硅钼杂多酸阴离子在水／硝基苯界面的转移。在pH＝1．1～5．3时，转移离子为H9Dy（SiMo11O39）24－．根据循环伏安结果计算得转移离子的标准电位差和Gibbs转移自由能分别为0．102V和－39．5kJ•ml-1，并由循环线性电流扫描计时电位法计算了转移离子的有关动力学参数，H9Dy（SiMo11O39）24-在水／硝基苯界面的转移属准可逆转移．

Abstract:

The transfer of bis-1:11 molybdosilicate heteropolyanion with dysprosium across the water/nitrobenzene interface has been investigated by chronopotentiometry with linear current scanning and cyclic voltammetry. The standard transfer potential and Gibbs energy estimated from cyclic voltammetry were 0.102V and -39.5kJ.mol-1, respectively. The kinetic parameters of the transfer were determinated by chronopotentiometry with linear current scanning.
