Abstract：

Indole　and　tryptophan　produce　electrogenerated　chemiluminescence　(ECL)　at　a　Pt　electrode　under　triangular　pulse　voltage　when　using　KCl　as　the　supporting　electrolyte;　the　intensity　was　enhanced　in　the　presence　of　ca.　10-2　mol　l-1　H2O2.　The　effects　of　electrochemical　parameters,　solution　and　interference　conditions　are　investigated　in　detail.　Under　the　optimum　conditions,　the　detection　limit　(signal:noise　=　3)　for　indole　and　tryptophan　was　1　x　10-7　mol　l-1,　with　the　linear　calibration　range　extending　up　to　8　x　10-5　mol　l-1.
