|Abstract:||The effect of Triton X-100 on anodic stripping voltammetry at a mercury film electrode (MFE) depends on the concentration of the Triton X-100 solution. At concentrations below the critical micellization concentration (c.m.c.), the effect that is seen is a decline in the stripping peak current and corresponding decline in sensitivity. This is due to the adsorption of surfactant on the MFE surface. At Triton X-100 concentrations above the c.m.c., however, the deactivation of the electrode is reversed and enhanced sensitivity and lower background currents are obtained. This work suggests the use of surfactants to modify advantageously electrode surfaces.|
