The kinetic method for estimation of alditols by cerium (IV) in acidic medium has been investigated spectrophotometrically at 360nm under pseudo-first order condition. The reaction was first order with respect to substrate and oxidant. The estimation has been done from the calibration plots obtained by using pseudo first order rate constant of the indicator reaction and also by fixed time and fixed absorbance method. The rate data was obtained for the indicator reaction under varying kinetic experimental conditions. Results of this study indicate that the estimated values for the simulated samples are consistent and reproducible with in ~ ± 1%.
