Sulfonated aromatic pollutants such as 1,5-naphthalenedisulfonic acid (NDS or Armstrong's acid) are persistent compounds and thus resist environmental breakdown and microbial treatment. This study investigated the photo-oxidative degradation of such a persistent polar pollutant in the absence and presence of H2O2. The degradation of aqueous NDS solutions by photolysis was found to be efficient only in the presence of H2O2. The combination of UV irradiation and H2O2 leads to progressive degradation of NDS, which is converted into new, more biodegradable and non-toxic species.
磺化芳香族污染物，如 1,5-萘二磺酸（NDS 或阿姆斯特朗酸），是持久性化合物，因此它们难以被环境破坏和微生物处理。本研究调查了在不存在和存在 H2O2 的情况下，这种持久性极性污染物的光氧化降解情况。研究发现，只有在存在 H2O2 的情况下，光解才能有效地降解水溶液中的 NDS。UV 照射和 H2O2 的组合导致 NDS 的逐步降解，生成新的、更具生物降解性和低毒性的物质。
