摘要：

Both the efficiency and pathways of nitrobenzene degradation induced by gamma-ray irradiation were significantly influenced by the addition of reactive species scavengers. Experimental results showed that the degradation of nitrobenzene was more favorable under oxidative conditions than under reductive conditions. Based on the product analysis by GC-MS, possible degradation mechanisms of nitrobenzene under both oxidative and reductive conditions were proposed.
