The kinetics of the reduction of bisulfite by surfactant myoglobin films were examined using chronoamperometry after the overall stoichiometry of the reduction was examined by coulometry. Surfactant films of myoglobin were formed on a graphite (HOPG) electrode. On this electrode, two waves were observed for myoglobin, corresponding to the Fe(III)/Fe(II) and Fe(II)/Fe(I) reductions. Cyclic volta...
The well-known methods for the determination of serum iron, which are based on colour reactions with bathophenanthroline disulfonate, Ferrozine® or Chromazurol B, require — even on a microscale — sample amounts between 0.1 and 1.0 nil of serum (1,2,3). These sample volumes are too large for paediatric purposes. Reduction of sample size is possible in flame atomic absorption spectrophotometry us...
Standard redox potentials, E8s and redox processes of U, Np and Pu ions in acidic aqueous solutions are reviewed and evaluated critically. The E8s of reversible redox processes, MO2 /MO2 and M/M (M: U, Np or Pu) adopted are those proposed mainly by Riglet et al. on the basis of the precise correction of formal potentials, E8 s, according to the improved theoretical approach to estimate the ac...
