Polylysine‐Catalyzed Hydrogen Evolution at Mercury Electrodes

“…The poorly developed presodium wave was then considered of little analytical use and polarography of proteins was focused on the Brdicka's catalytic response (BCR). Both the presodium wave and BCR were shown to be due to the catalytic hydrogen evolution [1][2][3][4][5][6]. Over several decades BCR was very intensively studied because of its potential application in cancer diagnostics, but was later abandoned because of a lack of specificity for cancer.…”

The apparent faradaic response in the impedance characteristics of the capacitive current at a streaming mercury electrode

“…The application of the streaming mercury electrode [1,2] in electrochemical practice is useful if a short-time electrolysis within the relatively negative potential range is required (as example for the formation or oxidation of the alkaline or alkaline-earth metals amalgams). Also in the studies of other electrode processes on mercury, for which attainment of the true steady-state requires the constant inflow of the reactants from the bulk and the removal of undesirable, accumulating reaction products [3,4], the streaming electrode can be the optimum solution of the above experimental problems.…”

Oscillopolarography of Mercaptopurine and Its Synthesis Intermediates Using a Commercial Oscilloscope and an Adapter Circuit

“…The first experiments in oscillopolarography (1,2) used alternating current to investigate the electrode processes in polarography and followed the changes in electrode potential on the oscilloscope. Since the commercial introduction1 of the polaroscope, papers have shown that the method is applicable to qualitative and quantitative analyses of inorganic and organic compounds, to the determination of decomposition kinetics, and to following fast electrode processes.…”
