| 中文摘要: |
| 采用活性炭纤维电极电吸附水中Fe3+,研究电压、Fe3+初始浓度、pH值、温度对电吸附去除水中Fe3+效果的影响。实验结果表明:随着电压升高,Fe3+去除率升高；Fe3+初始浓度越大,Fe3+去除率降低,但活性炭纤维的吸附容量增大；溶液的pH值偏碱性时,Fe3+的去除率较高；温度越高,Fe3+去除率也越高,但是温度高于40 ℃时,由于溶液蒸发,Fe3+浓度降低较慢。此外,活性炭纤维电极再生实验结果表明,活性炭纤维电吸附Fe3+之后电极具有良好的再生性。 |

In this study, the activated carbon fiber electrodes are used to remove Fe3+ in water by electro-adsorption and the influence of voltage,initial concentration of Fe3+, pH value, and temperature on the removal ratio of Fe3+ is investigated.
e results show that, with the increasing voltage, the Fe3+ removal ratio increases, that the bigger the initial concentration of Fe3+ is , the smaller the Fe3+ removal ratio is, but the adsorption capacity of the activated carbon fiber increases, that when the pH of the solution is alkaline, Fe3+ removal ratio increase with rising temperature , but when the temperature is higher than 40 ℃, Fe3 + concentration decreases slowly due to the evaporation of the solution.
addition, testing of the regeneration of activated carbon fiber indicates that the activated carbon fiber electrode, after used for electro-adsorption of Fe3+, has good reproducibility. |
