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 tem-perature on the removal ratio of Fe3 + is investigated.The 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 increa-ses,that when the pH of the solution is alkaline,Fe3 + removal ratio increase with rising tempera-ture ,but when the temperature is higher than 40 ℃,Fe3 + concentration decreases slowly due to the evaporation of the solution.In 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.
