Comparative electrochemical treatments of two chlorinated aliphatic hydrocarbons. Time course of the main reaction by-products

- DCA and TCA more quickly degraded by electro-Fenton with BDD than anodic oxidation.
- Faster mineralization of TCA compared to DCA.
- Reaction pathways include oxidative and cathodic reductive dechlorination steps.
- Chloroacetic, dichloroacetic, acetic, oxalic and formic acids are major by-products.
- Released Cl− is oxidized to ClO3− and mostly to ClO4− by bulk OH and BDD(OH).
