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-...

A charge transfer between Fe and Co in cobalt hexacyanoferrate has been observed for the first time by anatase doping. The charge transfer, which involves a spin transition at the Co site, is supported by high-resolution XANES spectra. EXAFS evidenced a consistent change (10%) of the Co-N first shell.

Mesoporous cobalt hexacyanoferrate nanocubes (meso-CoHCF) were prepared for the first time through a facile sacrificial template method. The CoHCF mesostructures possess a high specific surface area of 548.5 m²·g-1 and a large amount of mesopores, which enable fast mass transport of electrolyte and abundant energy storage sites. When evaluated as supercapacitor materials, the meso-CoHCF materia...

Cobalt(II)-hexacyanoferrates(II) with incorporated monovalent Na+, K + , N H i + and Cs+ ions have been synthetized. Chemical composition and structure of the unit cell of the crystallites have been determined by X-ray and I R analysis. It has been found that all crystallites containing the monovalent cations are isomorphous having an FCC structure, whereas the cobalt(II)-hexacyanoferrate(II) c...

An electrochemical sensor for amperometric detection of hydroxylamine was developed by electrodeposition of hybrid copper-cobalt hexacyanoferrate films on a glassy carbon electrode. The modified electrode could reduce the overpotential of the hydroxylamine oxidation by about 400 mV. This sensor exhibited a linear relationship between the response current and the hydroxylamine concentration in t...

Cobalt(II)-M-hexacyanoferrate(II), M = K, NH4, Cs, as synthetic sorbents have ion exchange properties selective for monovalent cations. They show a higher selectivity for the ions with larger crystal radius if the sorption takes place in dilute solutions, whereas in concentrated sulutions the selectivity sequence is reversed. The phenomenon is attributed to the differences in physico-chemical p...

A stable electroactive thin film of cobalt hexacyanoferrate (COHCF) was electrochemically deposited on the surface of a microband gold electrode. The cyclic voltammograms of CoHCF film indicate the presence of two redox peaks corresponding to the hexacyanoferrate(II/lII) redox couple. The electrochemical behaviour of CoHCF is related to the concentration of supporting electrolyte and counter-io...
