Coulometric titration with electrogenerated oxidants as a tool for evaluation of cognac and brandy antioxidant properties

Ziyatdinova G.; Salikhova I.; Budnikov H. (2014)

Stoichiometric coefficients for reactions of cognac antioxidants with coulometric titrants (electrogenerated bromine and hexacyanoferrate(III) ions) have been found. Ellagic and gallic acids react with both titrants while ...
New Electrochemistry-Based Approaches to Brandy Quality Evaluation Using Antioxidant Parameters

Ziyatdinova G.; Salikhova I.; Skorobogatova N.; Chibisova M.; Budnikov H. (2015)

© 2014, Springer Science+Business Media New York. The electrochemical approaches based on coulometric titration, differential pulse voltammetry (DPV), and chronoamperometry have been tested for applicability to evaluation ...
Novel Coulometric Approach to Evaluation of Total Free Polyphenols in Tea and Coffee Beverages in Presence of Milk Proteins

Ziyatdinova G.; Nizamova A.; Budnikov H. (2011)

Electrogenerated hexacyanoferrate(III) ions have been used as coulometric titrant for the determination of total free polyphenols in beverages. Stoichiometric coefficients of natural flavonoids (rutin, quercetin, and ...
Surfactant media for constant-current coulometry. Application for the determination of antioxidants in pharmaceuticals

Ziyatdinova G.; Ziganshina E.; Budnikov H. (2012)

Effect of surfactant presence on electrochemical generation of titrants has been evaluated and discussed for the first time. Cationic (1-dodecylpyridinium and cetylpyridinium bromide), anionic (sodium dodecyl sulfate) and ...
