Voltage fluctuations resulting from transfer of ions at liquid liquid and gel liquid interfaces were analyzed. For frequencies higher than the range 6-60 Hz the power spectra were not influenced by the presence of picrate ions in the solution to any major extent. In this range, the resistivity was found to be approximately proportional to the inverse frequency square, both in absence and in the presence of picrate. By using an equivalent circuit approach, the effect of the cell geometry on the resulting power spectra has been examined. Keywords Fluctuation analysis Liquid liquid interface Electrochemistry.
