| 摘 要： | 将小阴离子掺杂聚吡咯/活性炭(PPy/AC)复合电极与常规炭电极组装成非对称离子交换膜电容脱盐(MCDI)单元,研究了其对不同荷电量、水合半径离子的吸附性能差异。结果显示:当复合电极分别作为脱盐单元的正极或负极时,其电容吸附过程的离子尺寸依赖效应差异显著,这应该与复合电极氧化还原过程的孔径尺寸变化有关。

Research on polypyrrole/activated carbon composite electrode used for the electro-adsorbability for different ions |

| Abstract: | The small-anion-doped polypyrrole/activated carbon(PPy/AC) composite electrode and conventional po-rous carbon electrode are assembled as an asymmetric ion-exchange membrane capacitive deionization(MCDI) module. Its adsorption capacities for ions with different ion-charge and hydrated radius have been investigated. The experiments results indicate that when the composite electrode (PPy/AC) is used as positive or negative electrode of MCDI module,respectively,the ion size dependent effect of capacitive adsorption process is significantly different, which should be related to the change of the pore size of the composite electrode. |
