Photodegradation of polymers is induced by the action of light and is attributed to photochemical reactions arising from the absorption of UV radiation by carbonyl groups present on the polymer backbone. UV energy striking a target has been determined by using graphite. The bimolecular rate constants for the reaction between each amine drug and • OH ranged from (2.1 ± 0.2) × 10 9 to (8.7 ± 0.3) × 10 9 M −1 s −1. All of these results may be helpful for manufacturing, storing, and applying these substantial drugs, especially in their ocular formulations. The mechanisms for these reactions are generally very complex. The UV-VIS spectrum of MEL is characterized by an absorption band with a peak at 278 nm. In order to avoid photosensitive reactions, it is essential to understand the mechanism behind the photosensitizing properties of such substances before these drugs are introduced in clinical settings. These findings are significant for understanding the phototransformation processes of antiviral drugs and other organic pollutants in estuarine and coastal regions.
