Determination of carbohydrates by flow injection with direct chemiluminescence detection

Abstract

The oxidation of mono- and di-saccharides by permanganate in the presence of Mn^II leads to chemiluminescence. This can be used to determine individual sugars using flow injection giving a linear response over three orders of magnitude. Calibration data for the range 10^–4 to 10^–1 mol dm^–3 are reported for monosaccharides glucose, galactose, fructose, arabinose and xylose, for disaccharides lactose and sucrose, for sugar alcohol mannitol, for glycerol and, for comparison, ascorbic acid.
