TL;DR: Characterization of the electroactive process included an examination of the degree of reversibility and parameters such as the effect of pH, volume of aqueous phase and interference of a number of metal ions on the determination of indium have been studied in detail to optimize the conditions for determination.

Abstract: : Solutions were derived for 2 boundary-value problems corresponding to electrode processes controlled by semi-infinite linear diffusion and by the rates of 2 consecutive electrochemical reactions Two cases were considered: (1) two consecutive irreversible electrochemical reactions, and (2) electrode reactions involving a potential determining step The adaptation of the solutions for linear diffusion to the case of the dropping Hg electrode was discussed It was shown that mechanisms based on the assumptions in case 2 cannot be used in the interpretation of irreversible polarographic waves Considerations are presented on the significance of diagrams showing the variations of half-wave potentials with a parameter characterizing a substance in a series of organic substances Application is made to the reduction of chromate ion in 1 M NaOH; considerations indicate this reaction proceeds with the intermediate formation of Cr4+ (See also AD13646)

TL;DR: In this paper, the electroanalytical behavior of corticosteroids has been studied in different supporting electrolytes and the reduction patterns are established by examining pH profiles, by constantpotential coulometry, fast-sweep voltammetry, potentiometry with ion-selective electrodes and differential pulse polarography.

TL;DR: It was found that at neutral pH DNA-Os,bipy produces three redox couples in the potential range between 0 and -1 V (peaks I-III) and a cathodic peak at about -1.3 V (peak IV), which corresponds to the known differential pulse voltammetric (polarographic) peak of DNA- Os,L adducts for which catalytic hydrogen evolution is responsible.

TL;DR: Pseudouridine can be determined by differential pulse polarography in the concentration range 2.6 × 10−6 M and by differential-pulse cathodic stripping voltammetry at concentrations two orders of magnitude lower.
