摘　　要：为解决磁组装电极副电极极化不足的问题,本研究基于CNT/Fe_(3)O_(4)、Fe_(3)O_(4)/MnO_(2)、Fe_(3)O_(4)/Co_(3)O_(4)、Fe_(3)O_(4)/RuO_(2)及铁碳颗粒(FC)五种副电极构建了五类磁组装电极,考察了电气石对各电极电化学性能以及电化学氧化降解废水效率的影响.结果表明,电气石能够有效促进副电极的极化,显著增大电极活性面积(最高28.47%),提高酸性红G模拟废水的降解效率(最高108.06%)和实际石化废水的矿化效率(最高10.61%).To address the issue of insufficient polarization of auxiliary electrodes(AEs)in magnetically assembled electrodes,five types of magnetically assembled electrodes were constructed using five different AEs:CNT/Fe_(3)O_(4)、Fe_(3)O_(4)/MnO_(2)、Fe_(3)O_(4)/Co_(3)O_(4)、Fe_(3)O_(4)/RuO_(2),and ferrocarbon particles(FC).This study examined the effects of tourmaline on the electrochemical performance of each electrode and its impact on wastewater treatment efficiency.The results demonstrate that tourmaline can significantly enhance the polarization process of AEs,increase the active surface area of the electrodes by up to 28.47%,improve the degradation efficiency of simulated acid red G wastewater by up to 108.06%,and enhance the mineralization efficiency of real petrochemical wastewater by up to 10.61%.
