Leland and Powell also studied ECL obtained from reaction of [(bpy)3Ru]3+ with trialkylamines [47], Since the mechanism involves an electron transfer from the amine to Ru3+, there exists an inverse relationship between the first ionization potential of the amine and ECL intensity. The relative intensity of [(bpy)3Ru]2+ ECL was found to be ordered tertiary > secondary > primary. Quaternary ammonium ions and aromatic amines do not produce ECL with Ru(II) diimine complexes. Brune and Bobbitt subsequently reported the detection of amino acids by [(bpy)3Ru]2+ ECL [28,29], Employing capillary electrophoresis for separation, the presence of various amino acids can be detected directly by reaction with [(bpy)3Ru]3+ generated in situ with up to femtomo-lar sensitivity and with a selectivity for proline and leucine over other amino acids. The formation of an amine radical cation intermediate is characteristic of proposed mechanisms of both aliphatic amines and amino acids.

Wang and coworkers have also separated and detected three different groups of pollutants (nitrophenols, aromatic amines, and chlorophenols) by capillary electrophoresis on a glass microchip with amperometric detectimi using river and ground-water samples. In this case, the detected compounds were previously added. Five nitrophenol derivates were detected in 120 s with a glassy carbon electrode, three aromatic amines (4-aminophenol, 2-aminonaphthalene, and o-aminobenzoic acid) in 150 s with a boron-doped diamond thin-film detector,and phenol and three... 

Capillary electrophoresis has been used for the analysis of chiral pollutants, e.g., pesticides, polynuclear-aromatic hydrocarbons, amines, carbonyl compounds, surfactants, dyes, and other toxic compounds. Moreover, CE has also been utilized to separate the structural isomers of various...
