Methods using derivatives of chronopotentiograms

In principle, compensation of capacitive effects can be 100 per cent. The optimal pulse duration seems to be about 1 s. [Pg.213]

A theoretical description of this experiment has to take into account the existence of a faradaic current during the first pulse. For small values of t, one obtains, for only O or R present, the equation [Pg.213]

Double current steps, where the second step reverts to the initial value of the applied current, have been used in mechanistic studies11. [Pg.213]

If we consider reversible and irreversible systems, the derivatives dE/dt are easily obtained and are [Pg.213]

By measuring dE/dt we can calculate the transition time, t. The usefulness of these expressions is that they permit the determination of r in a region where the capacitive contribution is small (in fact at its minimum). [Pg.213]
