Combination of nanogravimetry and visible spectroscopy: A tool for the better understanding of electrochemical processes

The paper authored by B.B. Berkes, S. Vesztergom and G. Inzelt is published in Journal of Electroanalytical Chemistry (2013, vol. 719, pp. 41–46).

Abstract:

A new, software controlled electrochemical measuring system for the simultaneous measurements of surface mass changes and optical absorbance spectra has been developed. A usual EQCN apparatus with transparent ITO-covered quartz crystal working electrode was built in a three-electrode cell made of polyvinylidene fluoride. A detailed description of both the apparatus and the software are given in the paper. The system was tested by the deposition and electrochemical transformation of polyaniline films. A new insight into the properties of the system is given by introducing the molar absorptivity based on simultaneous mass an absorption measurements.
