Abstract

In this study, a new reaction system for quantitative determination of ASCORBIC ACID was introduced. The developed method is based on inhibitory effect of ASCORBIC ACID on the Orange G-bromate system. The change in absorbance was followed spectrophotometrically at 478 nm. The dependence of sensitivity on the reaction variables including reagents concentration, temperature and time was investigated. Under optimum experimental conditions, calibration curve was linear over the range 0.7 – 33.5 mg mL-1 of ASCORBIC ACID including two linear segments and the relative standard deviations (n=6) for 5.0 and 20.0 mg mL-1 of ASCORBIC ACID were 1.08 and 1.02%, respectively. The limit of detection was 0.21 mg mL-1 of ASCORBIC ACID. The effect of diverse species was also investigated. The developed method was successfully applied for the determination of ASCORBIC ACID in PHARMACEUTICAL SAMPLES. The results were in a good agreement with those of reference method.
