中文摘要	tris(2,2'-bipyridyl)ruthenium(ii) electrochemiluminescence (ecl) of glyoxal, glyoxylic acid, methylglyoxal and acetaldehyde has been investigated for the first time, and was compared with ecl of the well-known coreactant oxalate. glyoxal, glyoxylic acid and methylglyoxal are 4.4-times, 2.5-times and 2.3-times the ecl intensity of oxalate at glassy carbon electrode, respectively. based on their high ecl efficiencies, glyoxal, methylglyoxal, glyoxylic acid and acetaldehyde have been sensitively detected by ecl methods without the need of derivatization. the ecl intensities increase linearly with the concentrations of glyoxal, glyoxylic acid, methylglyoxal and acetaldehyde over the ranges of 1 mu m-10 mm, 1 mu m-5 mm, 1 mu m-5 mm and 0.3 mm-5 mm, respectively. electrochemistry studies show that electrogenerated hydroxyl radicals play important roles in ecl, and coreactant family can be expanded by taking advantage of the strong oxidation ability of electrogenerated hydroxyl radicals.
