Abstract：

The　electrochemiluminescent　(ECL)　behavior　of　lucigenin　on　a　multiwall　carbon　nanotubes　modified　glassy　carbon　electrode　(MWNT/GCE)　during　anodic　scanning　was　studied.　A　strong　and　stable　anodic　ECL　signal　was　found　on　MWNT　modified　electrode,　which　results　from　the　oxidation　reaction　between　lucigenin　and　the　oxidation　production　of　OH-.　The　effects　of　electrode　materials,　pH　and　scan　rate　on　the　ECL　intensity　were　studied,　and　the　possible　ECL　mechanism　was　also　proposed.　Under　the　optimized　conditions,　the　ECL　intensity　was　found　to　be　linear　with　concentration　of　lucigenin　in　the　range　of　5.0　×　10-7-5.0　×　10-6　mol/L　with　a　detection　limit　of　2.0　×　10-7　mol/L.　Superoxide　dimutase　(SOD)　was　found　to　be　able　to　inhibit　this　ECL　system,　based　on　which　a　sensitive　ECL　methods　for　detection　of　SOD　had　been　established.　©　2008　Elsevier　B.V.　All　rights　reserved.
