Abstract: | Carbon fibre microelectrodes were made by sealing the fibres into glass and by using heat-shrinkable tubing. The electrodes can be coated with mercury by deposition at ?0.9 V vs. SCE from 0.1 M thiocyanate containing 0.05 mM mercury(II) at pH 2.5. Coulometric measurements and square-wave voltammetry were used to establish the properties of the deposit. Conditions for the deposition and stripping of cadmium are outlined. |
