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.
Cyclic linear current sweep chronopotentiometry and cyclic voltammetry were used to study the transition of the double-1:11 dysprosium heteropoly-silicate heteropolyanions at the water / nitrobenzene interface. At pH = 1.1 ~ 5.3, the transfer ion is H9Dy (SiMo11O39) 24-. According to the cyclic voltammetry results, the standard potential difference and the Gibbs free energy of transfer ion were calculated to be 0.102V and -39.5kJ · ml-1, respectively, and the related kinetics of the transferred ions were calculated by cyclic linear current scanning chronopotentiometry The parameter, H9Dy (SiMo11O39) 24-transfer at the water / nitrobenzene interface is quasi reversible.
