4-dichlorobenzene in acetonitrile-aqueous solution was investigated on a platinum electrode.The cyclic voltammetric (CV) profiles showed that the oxidation potential region of 1
4-dichlorobenzene was about 2.0—2.3 V(vs SCE).Moreover
the effect of different scan rates on CV curves implied that oxidation reaction of 1
4-dichlorobenzene was controlled by diffusion process.Additionally
the major intermediates detected by liquid chromatography (LC) and liquid chromatography/mass spectrometry (LC/MS) were parachlorophenol
1
4-benzoquinone and 2
5-dichloro-p-benzoquinone.The variation of the concentrations of related anions (oxalate
acetate
formate
maleate and chloride ion) during the reaction process was ascertained by ion chromatography (IC).On the basis of these findings
two tentative degradation pathways
hydroxyl radical attacking of the atom of carbon in benzene ring and dechlorination of 1
