Abstract：

Electrochemiluminescence　(ECL)　based　on　allantoin　and　tris(2,2′-　bipyridine)ruthenium　(II)　[Ru(bpy)32+]　was　studied　in　aqueous　alkaline　buffer　solution　(pH　11.0).　In　a　flowing　system,　the　eluted　allantoin　was　mixed　with　1.0　mmol/L　Ru(bpy)32+.　When　the　solution　passed　through　a　thin　layer　flow　electrolytic　cell　equipped　with　a　glassy　carbon　disc　electrode　(22.1　mm2),　both　hydroxyl　groups　of　allantoin　and　Ru(bpy)32+　were　oxidized　at　the　potential　of　+1.50　V　(vs.　Ag/AgCl).　The　luminescence　with　λmax　610　nm　caused　by　the　reaction　of　electrolytically　formed　Ru(bpy)3　2+　with　alkoxide　radical　to　generate　the　excited　state　of　Ru(bpy)32+*,　A　possible　ECL　process　of　allantoin　in　Ru(bpy)32+　alkaline　solution　has　been　discussed.　In　addition,　the　factors　affecting　the　ECL　response　of　allantoin　are　also　investigated.　Copyright　©　2005　John　Wiley　&　Sons,　Ltd.
