In linear-sweep voltammetry, triangular-wave voltammetry, cyclic triangular-wave voltammetry, and similar techniques, the maximum value of the @[email protected] due to the reduction or @[email protected] 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 @[email protected] decreases monotonically, while the @[email protected] due to the reduction or @[email protected] 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 @[email protected] is smaller than the rate at which it is removed from the @[email protected] by electrolysis. The term has also been used to denote the maximum value of the @[email protected] attributable to the reduction or @[email protected] of an @[email protected] in techniques such as ac @[email protected], differential pulse @[email protected], and derivative @[email protected] However, these techniques give curves that arise in ways different from that cited above, and the terms summit, @[email protected], and @[email protected] are therefore recommended for use in connection with such techniques.
