ANALYTICAL PERFORMANCE OF DIFFERENTIAL-PULSE POLAROGRAPHY IN THE CASEOF NON-REVERSIBLE SIMPLE REACTIONS

The behaviour of quasi-reversible and irreversible waves for different ial pulse polarography (DPP) performed at dropping and static mercury drop electrodes, was studied as a function of the first polarization t ime, the pulse duration and the potential step amplitude. The experime ntal results confirm the theoretical predictions and show that for slo w reactions a decrease in the first polarization time and an increase in the potential step amplitude yield a real improvement in sensitivit y.
