摘要：

Ciprofloxacin (CIP) is one of the most important antibiotics in pharmaceutical companies' industrial drains and causes environmental pollution. In this work, a new photocatalyst based on g-C3N4/N, P CQD/ZIF-67 was synthesized for CIP photocatalytic degradation. The synthesized sample was characterized by field emission scanning electron microscopy, Fourier transform infrared spectrometer, and X-ray powder diffraction. Synthesized photocatalytic can degrade CIP as 98%. This degradation occurred in 90 mins. The results showed OH & DEG; and & DEG;O2 & DBLBOND; radicals have an important role in CIP degradation in pH = 6. Moreover, the bandgap evaluated for g-C3N4/N, P-CQD/ZIF-67 nanocomposite (1.3 eV) is less than gC3N4 and g-C3N4/N,P CQD, which indicates the faster movement of electrons in the synthesized nanocomposite, so g-C3N4/N,P CQD/ZIF-67 nanocomposite has good application in CIP degradation. The products of CIP degradation were analyzed by LC/MS-MS.& COPY; 2023 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V. All rights reserved.
