Overview

Comparative study shows UV-based AOPs effectively degrade pharmaceuticals, indicating optimal treatment methods.

Key Points

  • This study aims to compare the degradation behaviors of ribavirin and chloroquine phosphate using UV-based advanced oxidation processes.
  • Three UV/AOPs (UV/H2O2, UV/PMS, UV/KMnO4) were tested for degradation efficiency.
  • Radical pathways and the impact of different water matrices were assessed.
  • Degradation kinetics and electrical energy per order (EEO) were measured for both contaminants.
  • UV/H2O2 showed the best performance with low EEO values (0.59 kWh/m3 for RBV and 0.46 kWh/m3 for CQP).
  • UV/PMS exhibited faster kinetics but higher energy consumption (28.67 kWh/m3 for RBV at 0.4 mM).
  • Pollutant polarity significantly influenced degradation rates and radical mechanisms observed.
