石墨烯修饰微生物燃料电池降解十二烷基磺酸钠

The degradation of sodium dodecyl sulfate based on graphene-modified MFC

以十二烷基磺酸钠为阳极电子供体,同时以石墨烯为催化剂对电极进行修饰。将修饰前后微生物燃料电池的产电性能和十二烷基磺酸钠的降解情况进行对比,经过修饰的电极装置产电效率明显增大,最大电压增加了1倍,并使十二烷基磺酸钠的降解率从49.85%提高到65.11%。这说明用石墨烯修饰后的微生物燃料电池在稳定产电的同时降解十二烷基磺酸钠是可行的,为废水中阴离子表面活性剂的去除提供了新的方法与研究方向。

With sodium dodecyl sulfate as anode electron donor and graphene as catalyst to modify the electrodes,the production performance of MFC and the degradation rate of sodium dodecyl sulfate are compared before and after modification. The treatment effect of modified MFC is two times as the unmodified and the degradation of sodium dodecyl sulfate rate can reach 65. 11% from 49. 85%. The performance of MFC with graphene modify electrode and the rate of degradation of SDS was tested. It indicates a good effect with graphene modified MFC to degrade sodium dodecyl sulfate and provides a new orientation for removal of the kind of anionic surfactant in organic wastewater treatment.
