Oxidative Degradation of o-Chlorophenol with Contact Glow Discharges in Aqueous Solution

摘要

Contact glow discharge electrolysis (CGDE) of o-chlorophenol (2-CP) was investigated under different pH, voltages and initial concentrations. And the mechanism of the oxidation was explored. The results suggested that the degradation followed the first order kinetic law; Fe~(2+) had a remarkable catalytic effect on the removal rate of o-chloropenol. In the presence of Fe~(2+). 2-CP underwent an exhaustive degradation, from which the major intermediates included o-dihydroxybenze, p-hydroxybenze, p-benzoquione and carboxlic acids.
