Název v původním jazyce

Photostability of polycyclic aromatic hydrocarbons (PAHs) and nitrated polycyclic aromatic hydrocarbons (NPHs) in dichloromethane and isooctane solutions

Popis výsledku v původním jazyce

Kinetics of photodegradation of eight PAHs (naphthalene, anthracene, phenanthrene, pyrene, biphenyl, chrysene, benz[a]anthracene and tetracene) and five NPAHs (1-nitronaphthalene, 2 nitrofluorene, 9-nitroanthracene, 1-nitropyrene a 6-nitrochrysene) wasstudied in isooctane and dichloromethane solutions standing in a laboratory and in a light simulator. PAHs and NPAHs were divided into three groups according to their life times. Degradation of tested compounds was faster in dichloromethane compared withisooctane. Decomposition of NPAHs was easier than degradation of corresponding parent PAHs. The most frequent photoproducts were quinones, benzoic acid and other derivatives with hydroxyl, carbonyl and carboxyl groups for both PAHs and NPAHs. Chlorinatedderivatives of tested compounds were identified in dichloromethane. Degradation intermediates underwent in further oxidation, fragmentation, reduction or radical chlorine addition.
