Palladium-nickel　(Pd-Ni)　bimetallic　electrodes　were　prepared　by　electrodeposition　method　assisted　with　surfactants　of　cetyl　trimethyl　ammonium　bromide　(CTAB),　sodium　lauryl　sulfonate　(SLS)　or　sodium　dodecyl　sulfate　(SDS).　The　prepared　Pd-Ni　electrodes　were　characterized　in　terms　of　cyclic　voltammetry　(CV),　scanning　electron　microscope　(SEM),　X-ray　diffraction　(XRD),　and　inductively　coupled　plasma-atomic　emission　spectroscopy　(ICP-AES).　The　electrode　prepared　with　CTAB　assistance,　Pd-Ni(CTAB)/Ti,　with　higher　electrochemical　activity,　was　applied　to　the　dechlorination　of　pentachlorophenol　(PCP)　in　aqueous　solution.　The　influences　of　dechlorination　current　and　initial　pH　value　on　the　PCP　removal　were　studied.　Complete　removal　could　be　achieved　at　ambient　temperature　under　the　conditions　of　constant　current　of　3　mA　and　initial　pH　value　of　2.1　on　the　Pd-Ni(CTAB)/Ti　electrode　within　90　min.　Moreover,　decay　kinetics　and　apparent　activation　energy　of　PCP　dechlorination　were　investigated.　(C)　2014　Elsevier　B.V.　All　rights　reserved.
