A simple, rapid, and accurate spectrophotometric flow-injection method was developed for the determination of sorbic acid in wines based on the oxidation of sorbic acid with K 2 Cr 2 O 7 /H 2 SO 4 at 100ЊC, followed by reaction of the resulting malonaldehyde with thiobarbituric acid, also at 100ЊC,
High sensitivity is obtained by using high concentrations of gallic acid and bromate, although the uncatalyzed reaction is significant. Various reactant concentrations, reaction temperature, pH and residence times can be used to alter the linear calibration ranges and sensitivity for vanadium. With
