 The photocatalytic degradation of CIP from aquia solutions using CQD decorated on NCU Kodope Titania, NCUT CQD, was studded through two synthesis steps by Solgel and hydrothermal methods. The results showed that the complete removal of ciprofloxacin, CIP, 20 mg per litre, could be achieved at pH 7.0, NCUT CQD for weight percent, 0.8gL, and light intensity, 100 mW per square centimeter over 60-minute reaction time. The O2 and O radicals were identified as the primary reactive species during the decontamination process. The synth-sized photocatalyst could be recycled after six consecutive cycles of CIP decomposition with an insignificant decrease in performance. Pharmaceutical wastewater was treated through the optimum degradation conditions which showed the photocatalytic degradation eliminated 89% of COD and 75% of TOC within 180 minutes. In the effluent toxicity evaluation, the EC50 values for treated and untreated pharmaceutical wastewater increased from 62.50% to 140% indicating that the NCUT CQD for weight percent this system can effectively reduce the toxic effects of pharmaceutical wastewater on aquatic environments.
