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/Fe3O4、Fe3O4/MnO2、Fe3O4/Co3O4、Fe3O4/RuO2, 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%.
