  We propose a new experimental technique for cyclic voltammetry, based on the
first-order reversal curve (FORC) method for analysis of systems undergoing
hysteresis. The advantages of this electrochemical FORC (EC-FORC) technique are
demonstrated by applying it to dynamical models of electrochemical adsorption.
The method can not only differentiate between discontinuous and continuous
phase transitions, but can also quite accurately recover equilibrium behavior
from dynamic analysis of systems with a continuous phase transition.
Experimental data for EC-FORC analysis could easily be obtained by simple
reprogramming of a potentiostat designed for conventional cyclic-voltammetry
experiments.
