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 H 2 O 2 . The degradation of aqueous NDS solutions by photolysis was found...
Sulfonated aromatic pollutants such as Armstrong’s acid, or 1,5-naphthalenedisulfonic acid (NDS), are recalcitrant to environmental breakdown and microbial treatment. This study investigated the effects of H 2 O 2 concentration, pH, microwave (MW) power and irradiation time on the oxidative degradation of NDS in aqueous solutions. The formation of hydroxyl radicals as the active oxidant...
