摘要：
Herein, a CuNiFe LDHs/ BiO2-x composite photocatalyst was successfully synthesized using a hydrothermal method and applied to activate peroxymonosulfate to degrade ciprofloxacin under visible light irradiation. Owing to the synergistic effect of photocatalysis and PMS activation, a high removal efficiency of CIP up to 88. 3% was achieved. The prepared photocatalysts were characterized using XRD, FT-IR, SEM, XPS, UV-Vis DRS, and other methods. The optimal loading amount of CuNiFe LDHs was determined, and the effects of PMS dosage, initial pH value, and inorganic anions (Cl - , CO23- , and NO3- ) on the degradation were investigated. Electron paramagnetic resonance and free radical trapping experiments demonstrated that.OH and h + were the main active species for degrading CIP, and the possible degradation mechanism of the system was proposed. © 2023 Science Press.
