Аннотация

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 dodecylsulfate) and nonionic (Triton X100 and Brij? 35) surfactants as well as nonionic high molecular weight polymer (PEG 4000) do not react with the electrogenerated bromine, iodine and hexacyanoferrate(III) ions. The electrogenerated chlorine chemically interact with Triton X100 and Brij? 35. The allowable range of surfactants concentrations providing 100% current yield has been found. Chain-breaking low molecular weight antioxidants (ascorbic acid, rutin, a-tocopherol and retinol) were determined by reaction with the electrogenerated titrants in surfactant media. Simple, express and reliable coulometric approach for determination of a-tocopherol, rutin and ascorbic acid in pharmaceuticals using surfactant media has been developed.
