Electrochemical dechlorination of 2,4-dichlorophenol in aqueous solution on palladium-loaded meshed titanium electrode

摘要

Electrochemical dechlorination of 2,4-dichlorophenol (2,4-DCP) in aqueous solution wasninvestigated on palladium-loaded meshed titanium (Pd/Ti) electrode at ambient temperature.nPd/Ti electrode was prepared with an electrodepositing method. Scanning Electron Microscopen(SEM) micrographs show that Pd microparticles uniformly disperse on the meshed Ti supportingnelectrode with spheroidal structure. Dechlorination experimental results indicate that, in aqueousnsolution, with the current efficiency of 24.3%, the removal efficiency of 100 mg/L 2,4-DCP on Pd/Tinelectrode was 93.2% under the conditions of the dechlorination current of 5 mA andndechlorination time of 90 min. The effect of initial 2,4-DCP concentration was also investigated.
