Ultraviolet-visible spectral characterization and ANN modeling of aqueous sugar solutions: Clinical and environmental perspectives.

ABSTRACT: The characterization of aqueous sugar solutions using optical techniques offers a non-invasive, rapid, and reagent-free approach for concentration monitoring in both analytical and environmental contexts. In this study, aqueous D-glucose solutions at concentrations of 0.1, 0.2, 10, 20, and 40 g/mL were analyzed using an ultraviolet-visible-near-infrared spectrophotometer across the 200-1020 nm wavelength range. Although glucose exhibits inherently low absorbance in this spectral domain due to the absence of strong chromophoric groups, measurable trends were observed-particularly in the ultraviolet region below 400 nm-consistent with theoretical expectations based on the Beer-Lambert law. Absorbance intensity increased consistently with glucose concentration, and while no sharp absorbance p
