[Electrochemical hydrodehalogenation of pentachloraphenol in aqueous solution by porous titanium loaded Pd cathode].
A study on electrochemical hydrodehalogenation of pentachloraphenol in aqueous solutions was conducted on porous titanium loaded Pd cathode and the operational parameters were investigated. Chloride ions and phenol is the main products analyzed by GC-MS. Up to 100% electrochemical hydrodehalogenation can be achieved with more than 90% conversion to phenol. The result showed that current in the circle play the most important role of dehalogenation while the best parameter is 300mA in this study. Compared to current, the effect of pH value and flow rate on the current efficiency and energy consumption of dehalogenation is limited. Complete dehalogenation, high current efficiency, low energy consumption and operational convenience confirm the feasibility of this method.
