Pd　loaded　Ti　electrode　(Pd/Ti　electrode)　was　prepared　by　electrodeposition　method　and　was　applied　to　2,　4,　6-TCP　dechlorination.　The　dechlorination　parameters　were　investigated　by　means　of　single　factor　experiment　and　response　surface　analysis　methods.　Reaction　rate　constants　of　the　possible　steps　in　2,　4,　6-TCP　dechlorination　were　fitted　out　by　using　the　experimental　data.　The　optimized　dechlorination　condition　of　2,　4,　6-TCP　was　obtained.　i.e.,　current　was　5　mA,　supporting　electrolyte　Na2SO4　concentration　was　0.05　mol/L　and　initial　pH　of　catholyte　was　2.40.　Under　the　above　conditions,　2,　4,　6-TCP　with　a　concentration　of　80　mg/L　could　be　completely　dechlorinated　in　80　min.　Dechlorination　of　2,　4,　6-TCP　followed　pseudo　first　order　kinetics.　The　main　pathway　of　2,　4,　6-TCP　dechlorination　was　2,　4,　6-TCP→2,　6-DCP→2-CP→phenol.
