【摘要】 <正> 用γ射线破坏水中的污染物质,其实质是由γ射线引发自由基反应,使污染物因氧化而降解。对不同的污染物与反应体系,其辐照降解行为有较大差异。因此,被辐照污染物对辐照反应的特异性,在很大程度上决定着γ辐照作为水处理手段是否具有竞争力。更多还原

【Abstract】 The principal purpose of this paper is to describe degradative effect of nitrobenzene solution by using γ-ir-radiation with activated carbon. The static experimental results showed that decomposition of nitrobenzene was related to the dose rate as well as initial concentration and pH value of the solution. At same absorbed dose, lower dose rate, higher initial concentration and pH 7.7 of the solution could obtain higher degradative effect of nitrobenzene. The results of dynamic treatment of γ-irradiation with activated carbon absorption of nitrbbnzene were much better than irradiation of absorption alone.更多还原
