Abstract：

A　new　electrochemiluminescent　(ECL)　detection　system　equipped　with　an　electrically　controlled　heating　cylindrical　microelectrode　(HME)　was　developed　in　this　paper.　The　cylindrical　microelectrode　made　of　platinum　wire　(25　μm　in　diameter,　6　mm　in　long)　was　used　as　the　working　electrode　of　the　ECL　detection　system,　the　temperature　of　the　electrode　could　be　controlled　electrically.　The　Ru(bpy)32+-ECL　and　Ru(bpy)32+-C2O42--ECL　systems　were　used　to　evaluate　this　ECL　detection　system.　The　detection　limit　for　oxalate　was　found　to　be　3.0　×　10-4　mol/L　when　Te　(temperature　of　the　HME)　was　22　°C,　and　found　to　be　3.0　×　10-6　mol/L　at　80　°C,　which　indicates　that　the　detection　limit　can　be　improved　greatly　at　higher　Te,　based　on　which,　it　is　possible　to　establish　a　more　sensitive　method　for　measurement　of　ECL　by　using　a　heated　microelectrode.　©　2006　Elsevier　B.V.　All　rights　reserved.
