Abstract:The electrochemical behaviour of haemoglobin denatured using different concentrations of urea was investigated at the liquid|liquid interface. The reverse peak current varied with the concentration of urea, allowing the building of the unfolding curve, which compares well with UV-Vis absorbance results. Thermodynamic parameters, such as the change in free energy of folding in water, w G ∆ , and the index of the compactness of the protein, m, were extracted from the experimental data. The work here presents a simple electrochemical method for the study of protein unfolding by electrochemistry at the liquid | liquid interface.

“…46a is based on the voltammetric measurement of a semi-hydrophobic ion transfer of the known standard ion-transfer potential ∆ o w φ i o . The reference potential is then calculated from the measured reversible half-wave potential E 1/2 rev (57) where the activity coefficient term is estimated by using the Debye-Hückel theory, and the diffusion coefficients are evaluated from voltammetric measurements. Representative values of the standard ion-transfer potential that are based on voltammetric, partition, and solubility data are listed in Table 2.…”

This document provides an inventory of theoretical and methodological concepts in electrochemistry at the interface between two immiscible electrolyte solutions (ITIES). Definitions of basic relationships are given, together with recommendations for the preferred symbols, terminology, and nomenclature. Methods of study of ITIES are briefly described, current experimental problems are indicated, and representative experimental data are shown. The practical applications of electrochemistry at ITIES are summarized. CONTENTS

“…The membrane also stabilized the interface when the organic phase was stirred. A silver/silver borate reference electrode was used in the aqueous phase, and a silver/silver tetraphenylborate pseudo-reference electrode was used in the organic phase, the latter being prepared according to a method previously described [17]. Platinum gauze was used as the counter electrode in both phases.…”

Electrochemically controlled ion exchange: proton ion exchange with sodium zeolite X and A

Structural characterisation of proton-exchanged zeolites, prepared using ion-transfer at the liquid-liquid interface, is reported. Specifically, electrochemical exchange of protons for sodium with zeolites X and A is described: the structural integrity of the resultant materials was probed by solid-state NMR spectroscopy and temperature-dependent powder X-ray diffraction. It is shown that replacement of ca. 40 % of the Na + can be achieved using this approach for both zeolites; however, the results indicate that exchange is accompanied by significant structural degradation in the case of zeolite A, with proton exchange occurring at the amorphous regions of the sample. In contrast, zeolite X retains its structure, and the level of proton exchange is comparable with the highest levels reported using conventional chemical methods, highlighting the utility of the electrochemical approach.
