Instability of Cr(H2O)5Br2+ and Cr(H2O)5I2+ complexes formed by Cr2+ oxidation at mercury electrodes
TLDR
In this paper, the entropies of activation of these reactions are large and negative, which indicates that the transition states are highly organized, and this high instability was explained in terms of the adsorption of the transition state on mercury during the inner-sphere electron transfer.About:

The catalytic adsorptive stripping voltammetric determination of chromium with dtpa and nitrate
TL;DR: In this paper, the catalytic adsorptive stripping voltammetric determination of chromium using diethylenetriaminepentaacetic acid (DTPA) is only possible when chromium(III) is preliminarily oxidized to chromium (VI) which can be accomplished by UV-irradiation of the oxygen saturated solution at pH 6.0-7.0.

TL;DR: In this paper, the integral equations obtained from the boundary value problems were solved and extensive data were calculated which permit construction of stationary electrode polarograms from theory, making it possible to develop diagnostic criteria so that unknown systems can be characterized by studying the variation of peak current, half-peak potential, or ratio of anodic to cathodic peak currents as a function of rate of voltage scan.
