摘要：

The uncompensated cell resistance of six carbon paste compositions used in carbon paste electrodes was measured before and after treatment with a 0. 10% (w/v) aqueous surfactant solution. The surfactant treatment considerably lowered the paste uncompensated resistance by removing (or decreasing) the oily, insulating layer produced during the process of smoothing the electrode surface.
