A Highly Sensitive Kinetic Spectrophotometric Method for the Determination of Ascorbic Acid in Pharmaceutical Samples
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 investiga...
متن کاملAmperometric Determination of Ascorbic Acid in Pharmaceutical Formulations by a Reduced Graphene Oxide-cobalt Hexacyanoferrate Nanocomposite
Investigation of the redox properties of drugs and their determination are performed by electrochemical techniques. Data obtained from electrochemical techniques are often correlated with molecular structure and pharmacological activity of drugs. In this regard, different modified electrodes were applied as sensors for quantification of different drugs.A nanocomposite of reduced graphene oxide-...

متن کاملL-Ascorbic acid degradation by bacteria. VIII. All the pathway in the L-ascorbic acid metabolism.
The medium used contained 3g of substrate, 150ml of 1/15M phosphate buffer and 150ml of sterile distilled water. 0.5g (dry weight) of the adapted cells was added to the medium and the whole was incubated at 30•‹ for 20 hours. For detecting the intermediate products, paper chromatography was chiefly used. For developing the nonvolatile acids, n-butanol-acetic acid-water (4:1:1) was used and the ...
