Measurement of phenolic compounds (i.e., phenols, catechols, hydroquinones and benzoquinones) using electrogenerated chemiluminescence
The electrochemiluminescence (ECL) activity and trace-level determination of phenols, catechols, hydroquinones and benzoquinones have been investigated. Since ECL involves the electrochemical generation of excited states, it is a good indicator of electrochemical, electron-transfer and energy transfer processes at electrified interfaces. In solution, phenolic compounds efficiently quench Ru(bpy)32+ (bpy=2,2'-bipyridine) ECL. Initial studies highlighted the measurement of detection limits using the Ru(bpy)32+/TprA (TprA=tri-n-propylamine) ECL reaction sequence and variation of the phenolic system concentrations. The potential and wavelength dependence of the ECL emission in quencher compounds was also investigated. Findings and applications are discussed.
