peak current
In linear-sweep voltammetry,triangular-wave voltammetry,cyclic triangu-
lar-wave voltammetry,and similar techniques,the maximum value of the
faradaic current due to the reduction or oxidation of a substance B during
a single sweep.This maximum value is attained after an interval during
which the concentration of B at the electrode-solution interface decreases
monotonically,while the faradaic current due to the reduction or oxidation
of B increases monotonically,with time.It is attained before an interval
during which this current decreases monotonically with time because the
rate of transport of B toward the electrode-solution interface is smaller than
the rate at which it is removed from the interface by electrolysis.
The term has also been used to denote the maximum value of the faradaic
current attributable to the reduction or oxidation of an electroactive sub-
stance in techniques such as ac polarography,differential pulse polarogra-
phy,and derivative polarography.However,these techniques give curves
that arise in ways different from that cited above,and the terms summit,
summit current,and summit potential are therefore recommended for use
in connection with such techniques.
See also apex current.
