【Abstract】 Contact glow discharge electrolysis is a novel type of electrochemical process.The results showed that p chloronitrobenzene was smoothly oxidized and eventually degraded to carbon dioxide.Concentration and voltage plays an important role,pH value has no appreciable effect on the degradation of p chloronitrobenzene,and Fe 2+ has a remarkable catalytic effect.Some of intermediate products were analyzed by a high performance liquid chromatography(HPLC).A path of p chloronitrobenzene disappearance caused by plasma was proposed according to the detected intermediate products.更多还原
