Abstract：

Recently,　2-(dibutylamino)ethanol　(DBAE)　was　reported　to　be　a　more　efficient　co-reactant　than　the　widely　used　tripropylamine　(TPrA)　for　electrochemiluminescence　(ECL)　of　Ru(bpy)32　+.　Therefore,　the　new　Ru(bpy)32　+/DBAE　ECL　system　seemed　to　be　great　potential　for　its　application　in　analytical　chemistry.　Dopamine　(DA)　was　found　to　be　able　to　inhibit　the　ECL　of　Ru(bpy)32　+/DBAE　system.　Under　the　optimum　conditions,　the　logarithmic　plot　of　the　inhibited　ECL　versus　the　concentration　of　DA　was　linear　in　the　range　of　5　×　10-10-7　×　10-7　M　with　the　detection　limit　of　4.0　×　10-11　M.　A　mechanism　based　on　the　quenching　of　reductive-form　DBAE　by　DA-oxidation　products　was　proposed,　which　was　quite　different　from　the　mechanism　for　Ru(bpy)32　+/TPrA/DA　system　reported　previously.　©　2009　Elsevier　B.V.　All　rights　reserved.
