Comparison of ribavirin degradation in the UV/H₂O₂ and UV/PDS systems: Reaction mechanism, operational parameter and toxicity evaluation.

ABSTRACT: Residues in surface water of ribavirin, which used extensively during the COVID-19 pandemic, have become an emerging issue due to its adverse impact on the environment and human health. UV/H₂O₂ and UV/peroxydisulfate (PDS) have different degradation effects on ribavirin, and the same operational parameter have different effects on the two processes. In this study, the reaction mechanism and degradation efficiency for ribavirin were studied to compare the differences under UV/H₂O₂ and UV/PDS processes. We calculated the total rate constants of ribavirin with HO^• and SO₄ ^•- in the liquid phase as 2.73 × 10⁸ and 9.39 × 10⁵ M^-1s^-1. The density functional theory (DFT) calcula
