Tris(2,2′-bipyridyl)ruthenium(II) Electrochemiluminescence of Sugar Alcohols
Sugar alcohols are low-calorie sugar substitutes commonly used in sugar-free products. In this study, we report for the first time Ru(bpy)32+ electrochemiluminescence (ECL) of sugar alcohols. Ru(bpy)32+ ECL of sugar alcohols, including sorbitol, mannitol, isbitol (also called isomalt, isomaltitol, and palatinitol), maltitol, lactitol, xylitol, and erythritol, was investigated. The applicability of the Ru(bpy)32+ ECL system for sugar alcohol detection was demonstrated by using sorbitol as a representative analyte. The optimized system exhibited excellent analytical performance, with a wide linear detection range from 0.5 μM to 5 mM and a low detection limit of 0.026 μM (S/N = 3). In practical applications, the system demonstrated outstanding accuracy in detecting sorbitol in pharmaceutical samples, with recovery rates ranging from 97.75 to 104.00%. These findings establish the Ru(bpy)32+ ECL as an effective and sensitive method for the detection of sugar alcohols.
期刊介绍：
Analytical Chemistry, a peer-reviewed research journal, focuses on disseminating new and original knowledge across all branches of analytical chemistry. Fundamental articles may explore general principles of chemical measurement science and need not directly address existing or potential analytical methodology. They can be entirely theoretical or report experimental results. Contributions may cover various phases of analytical operations, including sampling, bioanalysis, electrochemistry, mass spectrometry, microscale and nanoscale systems, environmental analysis, separations, spectroscopy, chemical reactions and selectivity, instrumentation, imaging, surface analysis, and data processing. Papers discussing known analytical methods should present a significant, original application of the method, a notable improvement, or results on an important analyte.
