A novel fused-silica capillary dropping mercury electrode with long drop-time and its application on determination of critical micelle concentration
Original language description
A novel long drop time mercury electrode has been constructed from common fused-silica capillary (50um I.D., 360um E.D.). Proposed device provides reproducible mercury drops with typical lifetime 40-120 s. The electrode was used for a set of electrocapillary measurements aimed at determination of critical micelle concentration of anionic surfactants by a convection controlled drop-time technique. A critical micelle concentration of sodium dodecyl sulfate 5.6+-0.4mmolL?1 and 4.3+-0.4mmolL?1 were obtainedin 1mmolL?1 and 5mmolL?1 phosphate buffer (pH 7.0), respectively. The values were comparable to those obtained from conductometric measurements under the same conditions (7.0+-0.1mmolL?1 and 5.2+-0.1mmolL?1, respectively) and the difference was explained in accordance with theory of hemi-micelle formation.
