Abstract：

Hot　electron　induced　cathodic　electrochemiluminescence　(ECL)　was　found　at　a　disposable　CdS　modified　screen　printed　carbon　electrodes　(CdS-SPCEs)　during　cathodic　pulse　polarization.　The　ECL　behavior　of　the　modified　electrode　was　investigated　with　two　emissions　located　at　520　nm　and　580　nm.　The　CdS-SPCEs　show　very　stable　and　reproducible　ECL　signal.　The　ECL　intensity　was　linear　with　the　dissolved　oxygen　concentration　in　the　range　of　1.7-33　mg/L　with　a　detection　limit　of　0.02　mg/L　(S/N　=　3).　In　addition,　a　possible　mechanism　for　ECL　behavior　of　the　modified　electrode　was　proposed.　The　developed　method　can　be　applied　to　detect　the　dissolved　oxygen　concentration　or　biochemical　oxygen　demand　(BOD).　©　2011　Elsevier　B.V.
