摘要：
The effect of pH of irradiated aerated solutions and the presence of various concentrations of bicarbonate and nitrate on radiolytic degradation of 2,4-dichlorophenol in aqueous solutions with gamma-irradiation was examined using reversed phase HPLC and ion chromatography. The obtaining complete decomposition and dehalogenation of 2,4-dichlorophenol in the presence of naturally occurring inorganic scavengers may require to increase the irradiation dose in batch conditions up to 10 kGy. The presence of scavengers at different doses affects both efficiency of radiolytic degradation and its mechanism.
