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 کاملDetermination of L- Ascorbic Acid in Plasma by Voltammetric Method
Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). L-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...

متن کاملSelective Determination of Dopamine in the Presence of Ascorbic Acid and Uric Acid at Neutral pH Using a Silver Nanoparticles-modified Carbon Paste Electrode
Developing simple, sensitive and selective sensing systems for dopamine is important due to its biological significance. In this work, a silver nanoparticles-modified carbon paste electrode (AgNPs-CPE) has been constructed and used to detect of dopamine (DA) in the simultaneous presence of ascorbic acid (AA) and uric acid (UA) at neutral pH 7.0 by cyclic voltammetry. The modified electrode show...
