摘要

A kinetic study of the Winkler's reaction for the determination of 2-furfuraldehyde (FUR) has been made on the basis of the absorbance-time curves. Winkler's method has been modified and only one step is necessary to add all reactive components. A kinetic method for the determination of FUR was developed with a range of application between 0.12 and 2 mu g mL(-1). The proposed kinetic method permits one to determine FUR in spirit beverages without the instability problems of the conventional Winkler's method. Only, 40 s per sample is necessary for the analysis.
