Abstract

Based on the characteristics of persulfate (PS) activation that can quickly and effectively remove organic pollutants in water, a new catalytic material of carbon nitride supported Fe-Co diatom (FeCo@N-C) was prepared for PS activation to degrade orange II (OII). The XRD pattern showed that eight characteristic diffraction peaks, including CoFe₂O₄ diffraction absorption peaks. The FT-IR inferred that C-N/C=N, C=O, and O-H functional groups may exist. SEM observed the surface morphology of the synthetic material, and Fe and Co can be successfully loaded on the synthetic material. The activation effect of FeCo@N-C activator on PS was significantly improved, and the decoloration removal rate reached 81.66% at 20 min, 57% higher than the PS alone, FeCo@N-C activator had a good pH and temperature adaptability. FeCo@N-C activator could promoted the production of free radicals which can degrade OII efficiently.
