摘要：

Electrocatalytic　activity　of　palladium-nickel/polymeric　pyrrole　film　modified　titanium　(Pd-Ni/PPy/Ti)　electrode　for　the　electrochemically　reductive　dechlorination　of　chloroform　was　carried　out　in　aqueous　solution.　The　prepared　Pd-Ni/PPy/Ti　electrode　was　characterized　by　scanning　electron　microscopy　(SEM),　cyclic　voltammetry　(CV)　and　atomic　emission　spectrometry　(AES).　Pd-Ni　microparticles　were　uniformly　dispersed　on　a　polypyrrole　(PPy)　film　which　was　previously　electrodeposited　on　the　titanium　(Ti)　netting　supporting　electrode.　Electrocatalytic　reduction　of　chloroform　was　performed　in　a　two-compartment　cell　separated　by　cation-exchange　membrane.　It　is　found　that　the　removal　efficiency　of　chloroform　and　current　efficiency　on　Pd-Ni/PPy/Ti　electrode　could　be　up　to　52.10%　and　46.74%　at　dechlorination　current　of　0.1　mA　and　dechlorination　time　of　180　min.　©2009　IEEE.
