Polychlorinated naphthalenes (PCNs) are a new type of persistent organic pollutant (POP) characterized by persistence, bioaccumulation, dioxin-like toxicity, and long-range atmospheric transport. Focusing on one PCN, monochlorinated (CN-1, CN-2), this study aimed to examine their photodegradation in the environment. In work, CN-1 CN-2 were employed as model pollutants investigate process under UV-C irradiation. Factors like pH, initial concentrations CN-1, inorganic anions investigated. Next, roles hydroxyl radicals (•OH), superoxide anion (O2•−), singlet oxygen (1O2) discussed proposed via theory computation. The results show that follows pseudo-first-order kinetics. Acidic conditions promote while effects pH not remarkable. Cl−, NO3−, SO32− accelerate whereas effect SO42− CO32− is significant. Additionally, contributions •OH O2•− 20.47% 38.80%, while, for CN-2, contribution 16.40% 16.80%, respectively. Moreover, 1O2 15.7%. Based DFT calculations, C4 C6 benzene ring prioritized attack sites •OH, C2 C9 sites.
