A　single-sided　heated　graphite　cylindrical　electrode　(ss-HGCE)　was　designed.　Compared　to　previous　alternative　current　(AC)　heating,　much　simpler　and　cheaper　direct　current　(DC)　heating　supplier　was　adopted　for　the　first　time　to　perform　adsorptive　accumulation　of　rutin　at　ss-HGCE　at　elevated　electrode　temperature.　This　offers　great　promise　for　low　cost,　miniaturization　and　high　compatibility　with　portability.　The　square　wave　voltammetry　(SWV)　stripping　peak　current　was　enhanced　with　increasing　the　electrode　temperature　only　during　preconcentration　step.　This　enhancement　was　contributed　to　the　forced　thermal　convection　induced　by　heating　the　electrode　rather　than　the　bulk　solution,　which　is　able　to　improve　mass　transfer　and　facilitate　adsorption　hence　enhance　stripping　response.　A　detection　limit　of　1.0　x　10(-9)　M　(S/N　=　3)　could　be　obtained　at　an　electrode　temperature　of　48　degrees　C　during　5　min　accumulation,　one　magnitude　lower　than　that　at　28　degrees　C　(room　temperature).　This　is　the　lowest　value　at　carbon-based　electrodes　for　rutin　determination　as　we　know.　Such　novel　method　was　also　successfully　used　to　determine　rutin　in　pharmaceutical　tablets.　(C)　2008　Elsevier　Ltd.　All　rights　reserved.
