Abstract
The characteristic and mechanism of 2-chloroethanol degradation in a micro-electrolysis contact oxidation system were investigated. The degradation rate of 2-chloroethanol was higher in acid solution than that in neutral or alkaline solution. Addition of activated carbon could make 2-chloroethanol easier be degraded by the surface contact catalysis. The dissolved oxygen in solution could take part in the electrode reaction and intensify the degradation of 2-chloroethanol. Most intermediate products were chloroacetaldehyde, chloroacetic acid, glycollic acid, glyoxylic acid and ethanedioic acid. By the analysis of intermediates of degradation of 2-chloroethanol, its possible degradation pathway is proposed.
