Palladium/polymeric　pyrrole　film/foam-nickel　(Pd/PPy/foam-Ni)　composite　electrode　were　prepared　by　the　electrodeposition　method　with　the　electrodepositing　current　density　of　5　mA　x　cm(-2)　and　the　electrodepositing　time　of　40　min.　Electrochemical　reductive　dechlorination　of　chloroform　in　acidic　system　was　investigated　using　the　Pd/PPy/foam-Ni　electrode　at　ambient　temperature.　The　electrochemical　deposition　behaviors　of　Pd/PPy/foam-Ni　electrode　were　studied　by　means　of　cyclic　voltammetry　(CV).　Cyclic　voltammetry　results　reveal　that　the　large　hydrogen　adsorption　peak　current　of　-100　mA　on　Pd/PPy/foam-Ni　electrode　was　obtained　at　about　-500　mV　(vs　Hg/Hg2　SO4).　SEM　micrographs　show　that　the　addition　of　polymeric　pyrrole　changed　the　distributing　configuration　of　Pd　microparticles　on　the　electrode　and　Pd/PPy/foam-Ni　electrode　possessed　a　good　spatial　extension.　Chloroform　dechlorination　experimentes　were　conducted　in　acid　system.　Dechlorination　experimental　results　indicate　that,　with　the　integrated　analysis　of　removal　efficiency　and　current　efficiency,　with　the　high　current　efficiency　of　44.17%,　the　removal　efficiency　of　chloroform　on　Pd/PPy/foam-Ni　electrode　was　49.23%,　under　the　optimum　conditions　of　the　dechlorination　current　density　of　0.05　mA　x　cm(-2)　and　the　dechlorination　time　of　180　min.　In　acid　aqueous　solution,　with　low　initial　concentration　of　chloroform,　the　results　of　dechlorination　experiment　were　preferable.
