The inhibitory effect of various oral doses of different hexacyanoferrate(II) compounds (HCF) and the influence of the time interval of HCF-administration on intestinal 134Cs-absorption was studied in rats. Optimum inhibition was obtained by administration of HCF together with or 2 min before oral 134Cs loading. Using appropriate low amounts (0.1-0.5 mg) of the different HCF compounds, the inhi...

Nickel hexacyauoferrate films have been deposited on the surface of a microbaud gold electrode by cyclic voltammetry. Cyclic voltammograms of the resulting nickel hexacyauoferrate films indicate the presence of a couple of redox peaks which correspond to the hexacyanoferrate(II/III) redox couple. The nickel hexacyanoferrate modified microband gold electrode shows an excellent electrocatalytic a...

Pretreatment of mussel processing effluents for citric acid production by Aspergillus niger (CBS 262-65) in submerged culture was studied by means of an orthogonal full factorial experimental design with four independent variables: initial levels of hexacyanoferrate II, methanol, phosphate, and carbon source. The empirical model thus obtained showed the ineffectiveness of the hexacyanoferrate t...

A new, improved sensor for the electrocatalytic determination of ascorbate has been developed that has both a low applied operating potential and a low detection limit. The sensor was constructed by depositing copper hexacyanoferrate film either electrochemically or chemically onto carbon film electrode, and it was then characterised by cyclic voltammetry and electrochemical impedance spectrosc...
