Electrocatalytic Dechlorination of Chloroform in Aqueous Solution on Palladium/Titanium Electrode
Electrochemical dechlorination of chloroform in aqueous solution was investigated oil a palladium-loaded meshed titanium electrode at ambient temperature. The palladium/titanium (Pd/Ti) electrode, which provided a catalytic surface for reductive dechlorination of chloroform in aqueous solution, was prepared with art electrodepositing method. Scanning electron microscope (SEM) micrographs show that Pd microparticles uniformly disperse on the meshed Ti electrode with spheroidal structure. Dechlorination experimental results indicate that, in aqueous Solution with the high current efficiency of 33 %, the removal efficiency of chloroform on the Pd/Ti electrode was 37 %, under the conditions of a dechlorination current of 0.1 mA and dechlorination time of 180 min.
