PPT-Voltammetry and Polarography

1 Lecture 5 Differential Pulse Polarography In direct current polarography the voltage applied to the working electrode increases linearly with time The current is recorded continuously and a polarogram such as that shown previously results The shape of the plot is called a linear voltage ramp.

Stripping Methods . Stripping voltammetry methods are the most efficient electrochemical techniques for trace analysis. The unusually high sensitivity and selectivity are based on the fact that the analyte is accumulated before it is determined and that both accumulation and determination are electrochemical processes for which progress can be controlled. . 1.
